QT application periodically crashes at the destructors of std::thread and std::mutex when it is closed with 'back button' on the device with the following call stack:
and there are some other crashes, see [my blog post|https://developernote.com/2020/04/qt-app-crashes-at-the-destructor-of-std-thread-on-android-10/] for more information.
I discussed this on [stackoverflow.com|https://stackoverflow.com/questions/61321845/qt-app-crashes-at-the-destructor-of-stdthread-on-android-10-devices] and another developer confirmed that he has the same crashes in his app and found a workaround.
The workaround is to call System.exit(0) in Java code when 'back button' is pressed on the device (to prevent C++ deinitialization)
These crashes are hard to reproduce, so theoretically there can be some kind of a data race.
