Hi, qtwebengine crash while exit from my application. Qt5.9.0 and VS2017-win10.
Any help would be appreciated.

From posts I have seen elsewhere: this happens with QtWebEngine, sometimes. It seems to very picky about where it gets destroyed. If you are waiting for definitive answer, you might like to try moving around where/how you destroy it and see if different behaviour.
