Minimum code to repro
SUMMARY
I found this with Kdenlive when compiling it in MSYS2's UCRT64 in Windows. But
attached there's minimum reproducible code.
The application at exit displays the following message on the console before
waiting indefinitely:
`QEventDispatcherWin32::wakeUp: Failed to post a message (Invalid window
handle.)`
I don't know if that message is related to the issue.
The main thread stack when the application waits indefinitely:
