The interesting thing is that there is no test like this in test_umath.py. The closest thing is the second test in test_clog, which is (+0., 0.), (-inf, 0.). Does this vanish if you comment it out?
I think it's a weirdness in the way that Python can handle literals in the same statement.
If so, it seems like a platform-dependent quirk:
Python 2.5.2 (r252:60911, Apr 21 2008, 11:12:42) [GCC 4.2.3 (Ubuntu 4.2.3-2ubuntu7)] on linux2
Anyway, I marked the probable culprit as skipped for now.
We can define negzero=-0.0 at the top of the file and always use that.
