While if you look at the original failure ;-), you'll see that _both_
failure modes occur. The one I showed above occurs when test_optparse
runs the first time; the one you're thinking of occurs when regrest
*re*runs test_optparse in verbose mode. The original HPPA log
contained both failures.

Build 992 on the W2k trunk buildbot had only 46757 in its blamelist,
and was the first failing test run there.

What revision was your laptop at before the update? It could help a
lot to know the earliest revision at which this fails.

No, you're so argumentative today I'm starting to suspect it is ;-)

That's right -- none. If would be easy to check in a little temporary
tweak -- think I'll do that.

We don't, and I don't either. IIRC, Neil did quite a bit of that some
time ago, and he may have a script for it. Doing a binary search
under SVN should be very easy, given that a revision number identifies
the entire state of the repository.
