5.9.3 -> 5.9.4 regression: fa2a653 causes startup hang on Android

    XMLWordPrintable

Details

    Description

      The change fa2a653 (revealed by "git bisect"; code review https://codereview.qt-project.org/#/c/192566/) causes a startup hang on Android in my application whereby a call to QCoreApplication::postEvent, to post to the Qt thread, never succeeds. Reverting that commit fixes the problem.

      I haven't managed to come up with a small reproduction, and I can't post application source code.
