[Bug nptl/3610] New: coredump on pthread_mutex_lock()

["sources dot redhat dot com at hovland dot cx" <sourceware-bugzilla at sourceware dot org>]

There is a chance that glibc/nptl is not the cause of this, but I cannot say 
for sure. 
Note that this is glibc 2.5, not 2.4 as stated in the version field.
Thanks
