[Alban Browaeys]

reassign 814558 gdb
thanks

I did not set a version on gdb (this issue predates the git history).
Oldest git commit about this section of code is affected and is =

The issue is already fixed upstream https://sourceware.org/git/gitweb.c
gi?p=binutils-gdb.git;a=commit;f=gdb/python/py-
framefilter.c;h=30a7bb833cbd848b1814f18b91dfdafba4e86839
that is commit 	30a7bb833cbd848b1814f18b91dfdafba4e86839 "Fix
some error-handling bugs in python frame filters" but not yet in a
release (20161031).

upstream fix switches to get_addr_from_python and is more complete a
fix than my previous patch that only fix the current issue.
