Not much we can do without a way to reproduce it. Please report it upstream, bisecting it would be useful, and also testing with Qt6 if your application supports it.

Commit cb2da673f53815a5cfe15f50df49b98032429f9e breaks it for me. I'm unsure a what that change is actually good for or how it breaks thing. But I do find it suspisius that two delete operators are removed because of GCC 11.
