Problem with QWidget::accessibleName() (Qt 5.15.5)

Hello,

After compiling version 5.15.5 Qt, I observe several crashes on Android that seem to involve each time the QAccessibility module:

I have:

signal 11 (SIGSEGV), code 1 (SEGV_MAPERR)
QWidget::accessibleName() const

backtrace:
#00 pc 00000000001b7c24 /data/app/~~D-8AcLSq-5u8nRzxHrh4Tw==/xxxxx-uCEz8uo5GhzLe3zHc9PzDw==/lib/arm64/libQt5Widgets_arm64-v8a.so (QWidget::accessibleName() const)

I must add that I applied this path https://codereview.qt-project.org/c/qt/qtbase/+/410600 because I had already observed a problem with the QAccessibility module.

I had no such problem with version 5.15.2

Thanks!
