[issue41335] free(): invalid pointer in list_ass_item() in Python 3.7.3

[Steve Stagg]

Steve Stagg <stestagg at gmail.com> added the comment:

It's possible that RPi.GPIO (or another C extension) is mis-managing reference counts, resulting in it freeing or trying to free an object at the wrong time.  

If that object is a common value, or the branch that causes the refcount issue is uncommon, it may take many millions of cycles for the problem to occur.
