Description
We have a QApplication with a QMainwindow displaying QMessageBoxes.
If the user confirms the message, a new QMessagebox appears (just to simplify).
If the user just stays on the return key, after a few seconds the application hangs on OSX 10.12.
The endless loop is in
Qcocoaeventdispatcher.mm line 400:
while ([NSApp runModalSession:session] == NSRunContinuesResponse && !d->interrupt)
qt_mac_waitForMoreEvents(NSModalPanelRunLoopMode);
I tried the same with Qt5.8 but with no luck. After a while it crashes with output in Terminal:
