    Description

      Starting with PySide 6.7.0 classes with metaclasses fail at import time.

       

      from __future__ import annotations
      import abc
      from PySide6 import QtCore
      
      class MixinMeta(type(QtCore.QObject), abc.ABCMeta):  # type: ignore
          pass
      
      class CompareView(metaclass=MixinMeta):    def __init__(self, parent: QtCore.QObject=None):
              pass
          @abc.abstractmethod
          def update_view(self) -> None:
              raise NotImplementedError()
       
      [08:42 simon@simonlaptop local :)] python test_pyside.py 
      corrupted size vs. prev_size
      Aborted (core dumped) 

      after removal of abc.ABCMeta the result is this:

      [08:49 simon@simonlaptop local :)] python test_pyside.py 
      free(): corrupted unsorted chunks
      Aborted (core dumped)
