Yes, it works fine on my Pentium 4 with XP SP2, Python 2.4, NumPy 0.9.8,
SciPy 0.4.9.  What's your setup?

Hmmm ... it could be an ATLAS problem.  What's your processor?  I built
the SciPy 0.4.9 binaries against Pearu's ATLAS binaries for Pentium 2,
thinking that this would give maximum compatibility ...

Or perhaps it's something else.  Could someone with this problem please
post a backtrace?
