No minimal test case yet. ASAN says the widget's destructor is calling 
QObjectPrivate::deleteChildren(), which then says "attempting free on 
address which was not malloc()ed: 0x..."

Looking through the code, I don't see anything right away that could 
have been added as a child of this widget which was stack-allocated.

Interestingly, the stack trace shows that the widget's destructor is 
being called within one of its own methods. Whether it's the same widget 
or just the same class but a different instance, I'm not sure (ASAN's 
stack trace doesn't print this information.)

I'll take a closer look.
