im usually testing all my projects with ASAN and TSAN - all the non-Qt unit tests are clean ASAN is near to silent with my Qt tests but TSAN is giving a lot of warnings
do i need to build Qt from source (and maybe also GLib) with TSAN support or are there real problems in my code that i overlook i've reduced my original much bigger unit test down to a simple app with a thread that tunnels a signal using QMetaObject::invokeMethod over the application thread my system is a up-to-date Fedora 36 running freshly installed inside a VM Fedora default gcc (GCC) 12.2.1 20220819 (Red Hat 12.2.1-2) Fedora default Qt: Qt 5.15.6 Fedora default cmake version 3.22.2 im interested in understanding whats maybe wrong with My_application::post_command(char const*) - see the warning about this method in the TSAN log thanks for any help or tips all my project files on pastebin: https://pastebin.com/qFrMyhr4 [main.cpp] #include "my_application.h" #include <thread> int main(
