Are you getting the “Sigtrap Error Code”? If your answer is YES then don’t look further as we have got you covered.

Some people are experiencing the “Sigtrap Error Code” while trying to execute the programs.

Typically the “Sigtrap Error Code” appears when there is an issue with the program execution or the program is unable to find the proper instructions.

This error code generally occurred during the development or debugging process. If you are facing the “Sigtrap Error Code” while trying to use any web or application-based services then you can fix this issue by using the methods mentioned in this guide.

To know what those methods are and how they work, you need to keep on reading.

What Causes The Sigtrap Error Code?

There are several reasons that may cause the “Sigtrap Error Code” issue.

Missing Or Corrupted Files: You may be facing the “Sigtrap Error Code” problem while using the specific application or software because of missing or corrupted files. In that case, verifying and replacing the software files will possibly resolve your problem.

Incorrect Permissions: As I mentioned above, this error code usually occurs when there is an issue in program execution or improper instructions. This type of issue arrives when your software does not have the correct permission to execute certain tasks.

Bugs and Glitches: Bugs and glitches present in the software will cause many technical issues. It is possible that you are experiencing the “Sigtrap Error Code” problem because of the same reason.

Here are some effective to fix the “Sigtrap Error Code” problem.

Method 1: Restart Your Computer

One of the most common reasons for getting the “Sigtrap Error Code” Problem is bugs and glitches present in the software.

In that case, you can fix these temporary glitches by restarting your computer. So before you try any other method to fix the “Sigtrap Error Code” problem, we recommend you restart your computer first and see if the issue is fixed.

Method 2: Update the Software

If restarting your computer does not work for you then you can try updating the software. This will fix all bugs present in the software that may cause the “Sigtrap Error Code” problem.

Updating the software will resolve all bugs because every update comes with bug fixes and new features.

Method 3: Reinstall The Software

If you have tried both methods but still facing the “Sigtrap Error Code” problem then the last thing you need to do is uninstall the software and reinstall it again.

This will fix all problems caused by corrupted and missing files. Here is how you can uninstall the software in the Windows operating system.

First, close the software completely.
Open “Control Panel” and click on the Programs option.
Now, select the Program and Features option.
This will open the list of software installed on your device.

Hello,

I was not able to reproduce the issue (s. the screenshot). Have you tried it under Linux or Windows?

I would say, that the problem is the following part of your command: -p 5901:5901 -p 6901:6901 .

Bind to some other ports on your host, for example with the parameter -P, like

docker run --name=ubuntu -P accetto/ubuntu-vnc-xfce-chromium-g3

Then your container will use the next free TCP ports on your host. You can find out which ones with the command
docker ps.

Also make sure, that you have enough shared memory in the container. This Readme describes that at least 256MB is needed for Firefox. Maybe it’s similar also for Chrome. This WIki page describes how to check it.

Please let me know, if it helped.

Regards,
accetto

With processors that support instruction breakpoints or data watchpoints, the debugger will ask the CPU to watch for instruction accesses to a specific address, or data reads/writes to a specific address, and then run full-speed.

When the processor detects the event, it will trap into the kernel, and the kernel will send SIGTRAP to the process being debugged. Normally, SIGTRAP would kill the process, but because it is being debugged, the debugger will be notified of the signal and handle it, mostly by letting you inspect the state of the process before continuing execution.

With processors that don’t support breakpoints or watchpoints, the entire debugging environment is probably done through code interpretation and memory emulation, which is immensely slower. (I imagine clever tricks could be done by setting pagetable flags to forbid reading or writing, whichever needs to be trapped, and letting the kernel fix up the pagetables, signaling the debugger, and then restricting the page flags again. This could probably support near-arbitrary number of watchpoints and breakpoints, and run only marginally slower for cases when the watchpoint or breakpoint aren’t frequently accessed.)

The question I placed into the comment field looks apropos here, only because Windows isn’t actually sending a SIGTRAP, but rather signaling a breakpoint in its own native way. I assume when you’re debugging programs, that debug versions of system libraries are used, and ensure that memory accesses appear to make sense. You might have a bug in your program that is papered-over at runtime, but may in fact be causing further problems elsewhere.

I haven’t done development on Windows, but perhaps you could get further details by looking through your Windows Event Log?

Скомпилировал проект, нахожусь в режиме отладчика. Сама прога падает (не запускается). Debugger останавливается на строчке вида «delete[] a;». Выдает: «Program received signal SIGTRAP, Trace/breakpoint trap.». Читал, что это реакция на breakpoint, но я никакие breakpont’ы не ставил. Сработало какое-то исключение? Если да, то какое в принципе могло возникнуть, если a — массив указателей на экземпляры некоторого класса?

Проблема в функции void take_memory.

            new_cells = (cell**)memmove(new_cells, cells, cells_count * sizeof(cell*));
            delete [] cells;
            for(int i = cells_count; i < cells_count + added_count + 1; ++i) {new_cells[i] = NULL;}
            cells_count += added_count;
            cells = new_cells;
            return;
        }
    case 1:
        {
            border** new_borders = new border* [added_count + borders_count];
            borders_capacity = added_count + borders_count;
            assert(new_borders != NULL);
            new_borders = (border**)memmove(new_borders, borders, borders_count * sizeof(border*));
            delete [] borders;
            for(int i = borders_count; i < borders_count + added_count + 1; ++i) {new_borders[i] = NULL;}
            borders_count += added_count;
            borders = new_borders;
            return;
        }
    }

cells этот корректное значение содержит? Инициализация правильная?

Конструктор по умолчанию инициализурует NULL’ом. Затем вызывается функция add_cell, которая добавляет объект:

C++

void coordinate_plane::add_cell(cell& c)
{
    if(cells_count + 1 > cells_capacity)
    {
        take_memory(0, adding_count_of_cells_and_borders);
    }
    cells[cells_count] = &c;
    ++cells_count;
}

Ругается на delete, нет ли проблемы в memmove? Один из аргументов NULL.

Не думаю, что memmove при копировании нуля байт даст ошибку. Ну вставь условие туда, чтобы пропускать копирование, если cells == NULL.

Какой-то странный у тебя конструктор. Предполагается возможность передачи всех параметров извне, что ли? Даже указателей?

проблема может быть и в другом месте тоже. а в этом месте у вас она просто проявляется.
ну например по ходу дела в другом месте при каком-то условии delete[] для этого же cells уже было вызвано.
лучше весь код закинуть сюда. и желательно чтобы его можно было собрать и запустить без ввода чего-бы то ни было руками.

и еще: вот у вас в сигнатурах есть вектора. т.е. вы знаете что это такое. зачем же связались с самопальным динамическим выделением массивов? в случае с векторами это все заменилось бы на что-нибудь типа:

C++

1	cells.resize(cels.size() + added_count);

вот тут разве не выход за пределы:

C++

1
2
3

 for(int i = cells_count; i < cells_count + added_count + 1; ++i) {new_cells[i] = NULL;}
 
//  i < cells_count + added_count + 1 - зачем тут +1?

Просто не нужно брать управление памятью на себя. Используйте вектор, либо array если размер не меняется и известен на стадии компиляции. Сами себе яму роете. Проблемы с памятью могут вообще не проявляться до поры до времени, а могут проявляться совершенно в другой части программы.
