I have a project that I have been working for some time. Today I did try to enable Projects / Run / Run in terminal. When I check "Run in terminal" and start debug session, I crash every time I need to execute/spawn thread. The same code work just fine when "Run in terminal" is unchecked. Please see attached crash screen shot. This used to work fine couple of weeks ago. Since then I only updated system and installed clang. But I am not using clang to build. Actually g++ is only auto detected by Qt Creator (please see attached screenshot)

try

catch(const std::system_error& ex)

Also here is my

$ cat ~/.gdbinit
#handle SIGINT nostop
#handle SIGINT pass
#handle SIGINT print

I also did try to remove all Qt entries in  ~/.config/ to make sure some configuration got corrupted. But that did not help.
