Debugging in Qt creator gives SIGABRT



  • I'm sure I'm not the first one to report this, but I haven't found any related posts.
    I am developing a simple multi-threaded application in Qt Creator (two threads).
    My second thread, worker thread, has multiple references to Qt Vectors.
    When triggering breakpoints in that thread. Qt frequently displays a message box
    saying SIGABRT. Usually at this point the Qt debugger hangs. If it doesn't I can see
    the SIGABRT is triggered by an "index out of range" error in a Qt Vector. However, the error is not in my code. I suspect the error is in Qt debugger itself and that the error is triggered while trying to evaluate a symbol or expression for display. Its very frustrating. It makes it impossible to debug using QT debugger. I'm forced to use printf's or the equivalent.
    Is there a way to suppress the assert in the Qt Vector. Is there a way to prevent the debugger from hanging?
    If I'm posting in the wrong place, please point me to the proper location.
    Thanks in advance.

    However, the error is not in my code

    Even if it breaks inside Qt the source of the issue still can be in your code.
    Please post a stack trace after the crash.
    Also: does a debug build run without debugging without crashes?

    @C-Cubed What OS, what target OS and what QtCreator, what Qt version and what debugger are we talking about here ?
