For what it's worth, I'm seeing core dumps with both pthreads-using
applications I use (xmms and Mozilla) in this spot, on a uniprocessor
system.  (Well, it's actually a dual-CPU box, but the kernel only
supports one of them.)  This system was running well with a complete
(kernel, userland and packages) environment CVS-ed Friday morning EU
time, but fails after updating again today, Monday morning.

Installing the new libpthread.so introduced the behaviour, and
completely rebuilding everything that used it (including all
supporting libraries &c) did not help.
