Hello,
when running the unittests on a Debian sid machine with python2.7 and latest 
release of regex I got this error:

I'm on AMD64, so 64-bit little-endian

I've managed to reproduce the problem, but I'm puzzled as to why it's failing 
when it succeeds for Python 3.3 and the relevant code for matching is the same 
across both versions!

Is it 32-bit or 64-bit? Little-endian or big-endian?

It's a 'heisenbug': any attempt to debug makes it disappear. This could take a 
while... :-(
