Description
The bug happens when trying to use Q_OBJECT_BINDABLE_PROPERTY.
It finally goes down to function QtPrivate::QPropertyBindingData::d(). At the time of function quintptr d() const
{ return d_ref(); }trying to return, application crashes because of read access violation at (usually) 0x[all Fs]. The reason is believed to be a dangling pointer.
Using MSVC 100% reproduces the bug. MinGW seems fine so far (maybe just luck).
Use the attached sample to reproduce the issue.
