Ok, don't hesitate to report it.
qnsview_cast is using Obj-C RTTI. An object with a type inheriting QNSView will
pass isKindOfClass:[QNSView class] test.
Best regards,
Timur.

Hello Timur,
I was planning to, but after I gather some more observations, to get an idea if
indeed the foreign NSView gets released before calling the
QMacCocoaViewContainer dtor, and where. I also want to try to get some
certainty that we're not talking simply talking about a regression in Qt
Designer.
What is definitely new in 5.8 is qnsview_cast(), which I think warns a bit too
enthusiastically about casting something not a QNSView*. It's not related to
this crash, but shouldn't it at least accept instances of classes that inherit
QNSView*? A simple cast won't fool the ObjC runtime anyway.
