William Pickard <lollol22...@gmail.com> added the comment:
Jumping in here to explain why '__class' doesn't crash when '__sizeof__' does:
When '__class__' is fetched, it returns a new reference to the object's type.
When '__sizeof__' is fetched on the otherhand, a new object is allocated on the
heap ('types.MethodType') and is returned to the caller.
This object also has a '__sizeof__' that does the same (as it's implemented on
'object'.
So yes, you are exhausting the C runtime stack by de-allocating over a THOUSAND
objects.
You can see this happen by watching the memory usage of Python steadily climb.
