New submission from Jeffrey Walton:
Downloaded Python-3.4.0rc3. Compiled with Clang 3.4, added -fsanitzie=undefined

might be the reason for `-fwrapv`.

Checkout is complete. Working through a build now.
Could you look at http://bugs.python.org/issue20930 and advise on the best way
to proceed?

My bad. I managed to download a file named Python-3.4.0rc3.tgz this morning
(the tarball is still in my downloads). I'm not sure from where since
http://www.python.org/download/ does not have it

That's indeed the latest release, but the default branch will become 3.4.1.
