> Here's the other problem: it's possible for threads to simply disappear on Windows. Given that I see "dllmain" in the backtrace (though not DllMain), I can't rule out that this has happened. Qt 5.6 has a workaround to another deadlock caused by Windows. Can you try to cherry-pick 3ec57107cedb154f256e3ad001ea5475cc64fa94 from 5.8? With 3ec57107cedb154f256e3ad001ea5475cc64fa94 applied: Still dead-locking, same backtrace.
