Forget it, by digging irc logs I found
.  This issue is first of all a bug in compile_done_with_this_frame() which
should be prepared to receive None from compile_new_bridge().

I agree that what you're investigating looks a bit strange too, but that's more
likely not a bug in optimizeopt at all, but an issue with the fact that calling
several times W_TypeObject._pure_lookup_where_with_method_cache() with the same
arguments does not always return the same thing (which is strange).
