    Description

      [Windows]: When a library using QCoreApplication is unloaded and then loaded again it can cause a crash.

      This is down to the QCoreApplication::applicationFilePath() which has a static const char pointer to d->argv[0] which is not copied. When the library is loaded the second time then this can be pointing to invalid memory.
