GNU libc version 2.3.2 has a bug[1] "feclearexcept() error on CPUs with SSE" (fixed in 2.3.3) which has been submitted to Debian[2] but not fixed in sarge.
See http://www.its.caltech.edu/~astraw/coding.html#id3 for more information and .debs which fix the problem. [1] http://sources.redhat.com/bugzilla/show_bug.cgi?id=10 [2] http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=279294 If only somebody could show how this was a security issue, we could get Debian to finally release a fix in sarge for this (frequently asked) question.
