Re: floating point exception weirdness (Andrew Straw)
Just a small addendum, (which I hope will spur on bug-fixing once Todd et al. are back from the conference -- let me know if I should file a sourceforge bug report):
I've not read all this thread so I don't know the full background. But I had a floating point / SSE problem using numarray.
It turned out to be a glibc not numarray problem and was solved by upgrading glibc. http://sources.redhat.com/bugzilla/show_bug.cgi?id=10 There was also a SourceForge bug report but I can't locate it.
Regards Steve

The test code you filed with the RedHat bugzilla report at the URL you gave (above) does indeed produce the bug you mention in that bug report. So, I now think this is not a numarray bug, but a debian/libc bug.
Thanks for your help, Steve -- I never would have found this myself.
Now thinking about how to fix my glibc... Andrew
I filed a bug report on this with the Debian bug tracking system. (See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=279294 ) It looks like it's fixed in the upstream glibc sources -- the Debian maintainers just have to apply the patch, so hopefully it won't take too long.
Cheers! Andrew
