Hello,
I need a suggestion how to narrow down a crash which occurs on Mac 10.11.4, Qt 5.6.
I have QQuickView with complex UI structure. When a QQuickView is closed and the second one (with the same qml) opens
the app crashes with the following call stack.
1 QV4::QQmlValueTypeWrapper const const * QV4::Value::as<QV4::QQmlValueTypeWrapper const>() const qv4value_p.h 350 0x1064d7318
2 QQmlBinding::write(QQmlPropertyData const&, QV4::Value const&, bool, QFlags<QQmlPropertyPrivate::WriteFlag>) qqmlbinding.cpp 257 0x1064d5a73
3 QQmlBinding::update(QFlags<QQmlPropertyPrivate::WriteFlag>) qqmlbinding.cpp 191 0x1064d5137
4 QQmlBinding::setEnabled(bool, QFlags<QQmlPropertyPrivate::WriteFlag>) qqmlbinding.cpp 412 0x1064d6b99
5 QQmlObjectCreator::finalize(QQmlInstantiationInterrupt&) qqmlobjectcreator.cpp 1190 0x1064e8483
6 QQmlIncubatorPrivate::incubate(QQmlInstantiationInterrupt&) qqmlincubator.cpp 348 0x1064484a2
7 QQmlIncubationController::incubateFor(int) qqmlincubator.cpp 395 0x106449278
8 QQuickWindowIncubationController::incubate() qquickwindow.cpp 136 0x10480f2a5

... <More>
Unfortunately, I couldn’t manage to reproduce the crash on a test app.
So, maybe one of you could help me to narrow the issue down?
PS: I didn’t receive any feedback either from the support nor from the interest mailing list.
Thanks, Kirill Klochkov
