    bpo-44184: Fix subtype_dealloc() for freed type (GH-26274)
    
    Fix a crash at Python exit when a deallocator function removes the
    last strong reference to a heap type.
    
    Don't read type memory after calling basedealloc() since
    basedealloc() can deallocate the type and free its memory.
    
    _PyMem_IsPtrFreed() argument is now constant.

----------
resolution:  -> fixed
stage: patch review -> resolved
