Description
Our product is in beta testing with Qt 5.1, built from the stable branch within the last couple of weeks.
We have received several crashes in OS X that are related to accessibility. I don't think we got any similar crashes when we were building against 5.0.
I am attaching three crash reports. Two appear to be with QAccessibleWidget::state() and another in QAccessibleWidget::childCount() which may or may not be related.
So far we haven't been able to duplicate it ourselves, so I don't have steps to reproduce.
Here is the stack for one of the crashes:
