libc6: feclearexcept() error on CPUs with SSE


I can confirm that the numarray version of matplotlib
( 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.


1) a test program and the patch is at

2) the problem in the context of numarray is described at

I hope this helps,
