This got me thinking: it would be really nice if we could setup an 
automated bisection test.

We could start with something like:

- known good revision: 117923 (gcc4.2 branch)
- known bad revision: 131704

This gives us 13781 revisions to test. By bisecting, we should be able 
to lock in on the offending patch in less than 14 attempts. A script 
that automated this bisection process (checkout middle revision, test 
it, mark good/bad) would be great to find what exectly caused specific 
regressions.

I may give it a try tomorrow,
