Debugging in Qt creator gives SIGABRT

C-Cubed

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.

@C-Cubed said in Debugging in Qt creator gives SIGABRT:

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 ?

@jsulm
I read my posting afterwards and thought I had been overly terse
I am running Ubuntu 23.10 with QTCreator 12.0.2 and the tool's integrale debugger (it looks and feels like gdb). I can build, run and debug my functional code but when I try to incorporate the GUI aspects of my project

if I build from within QTCreator I get linking errors along the lines of ":-1: error: /snap/core20/current/lib/x86_64-linux-gnu/libpthread.so.0: undefined reference to `__libc_pthread_init@GLIBC_PRIVATE'"

If I run make from the command line the product builds fine and is executable popping up the GUI. In the make output the process makes no /snap/core20/current but uses /usr/lib to get at the *.so.0 files.

from this I conclude I am possibly referencing the wrong object files inside QtCreator, but I have not hit on the correct way to access the reference the correct files and complete the build.

@WildWilts Can you show your Kit and Qt configurations in QtCreator?
