Hello,
I can confirm that the numarray version of matplotlib
(http://matplotlib.sourceforge.net/) crashes for me without this
patch, and does not crash any more after I applied the patch.
My setup: libc6 version 2.3.2.ds1-18, a Pentium 4 processor (has SSE)
and the atlas3-sse2 library installed.
references:
1) a test program and the patch is at
http://sources.redhat.com/bugzilla/show_bug.cgi?id=10
2) the problem in the context of numarray is described at
http://sourceforge.net/tracker/index.php?func=detail&aid=870660&group_id=1369&atid=450446
I hope this helps,
Jochen
