Fred Drake 31f4d1fa4b Remove an unnecessary check for NULL. 2001-10-18 19:21:46 +00:00
Fred Drake 73006d0237 When weakref proxies are involved in binary & ternary slot operations, 
the left-hand operand may not be the proxy in all cases.  If it isn't,
we end up doing two things: a) unwrapping something that isn't a
PyWeakReference (later resulting in a core dump) and b) passing a
proxy as the right-hand operand anyway, even though that can't be
handled by the actual handler (maybe eventually causing a core dump).

This is fixed by always unwrapping all the proxies involved before
passing anything to the actual handler.
