SF bug 839548: Bug in type's GC handling causes segfaults.
...
Also SF patch 843455.
This is a critical bugfix.
I'll backport to 2.3 maint, but not beyond that. The bugs this fixes
have been there since weakrefs were introduced.

Remove proxy_print(), since that caused an inconsistency between
...
"print repr(proxy(a))" and "proxy(a)" at an interactive prompt.
Closes SF bug #722763 .

- The repr() of a weakref object now shows the __name__ attribute of
...
the referenced object, if it has one.
Also use %p to format pointers consistently, and use <weakproxy ...>
in proxy_repr(), to match the type name.

Remove weakref free list. This has the side effect of fixing a memory
...
management bug. Also, move some duplicated code into the new_weakref
fucntion.

proxy_compare(): Make sure that we unwrap both objects being compared if
...
both are proxy objects.

Make sure that when we invoke callback functions associated with weak
...
references, we do not allow any outstanding exceptions "leak" into the
callback's execution state.
This closes SF bug #478534 .

Referencable is not a word, so don't use it in an error message <wink>.

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.
