FWIW I looked at these patches yesterday when I was trying to reproduce
the bug, but did not find anything interesting. It's mostly for stuff in
the standard library. I haven't tried building Python with all of of
these patches though, and did not find an easy way to rebuild a SRPM on
a Debian system. I'm also wondering if it can be a 32 vs 64 bit issue?...
