Application works on Windows, but freezes on certain operations in Linux
-
I am running my Qt application in Qt Creator under Qt 5.12.3 with a CentOS 8 operating system. The application uses threading and I think this could be the issue, for Linux will handle threads differently than Windows. I've tried every QThread::Priority enum value and nothing seems to work. I have not posted code for this because it is an enormous code base. Has anyone experienced this where the application works fine on Windows but crashes on Linux?

It freezes or it crashes? These are 2 separate problems.
If it crashes, use asan (address sanitizer) to find the crash and other memory leaks.
If it freezes, use tsan (thread sanitizer) to find out why it's freezing.

Unfortunately I am compiling using MinGW 7.3.0 64-bit, so I don't believe I can use either.
As for crash vs freeze.. when I click the button I am trying to use the application will freeze, become unresponsive, then I have to force shutdown. In Qt Creator I just get "The program unexpectedly finished. The process was ended forcefully. ....\Application crashed. "

Doesn't MinGW support asan? It's GCC after all.
Anyway, since Qt is cross-platform you can compile your app with GCC or clang and use asan/ tbsan to nail down the problem.
