Please don't file a duplicate bug about this problem as we're well aware
of the existing bug. The big problem is that we don't seem to be able to
reproduce the bug as everything seems fine in our testing using
glibc-2.3.5*.

At least 3 Gentoo developers (myself included) have tried to reproduce
it without any luck which makes it quite hard to fix.

So what I'd like is a bit more information about the machines this
problem happens on. Model of the box, glibc version, kernel version and
patchset and output from emerge --info.

Please add all this info to bug 100259 or send it to this list or me
directly at kloeri@g.o and I'll see if I can find some pattern
to this. Hopefully this will give me some much needed clue about this
problem.

Regards,
Bryan Østergaard
