Since it is consistant, and since you can catch it under gdb
(which is very good), could you get a backtrace after the
segfault?  Any chance of compiling uClibc with DODEBUG enabled
and reproducing the segfault?  That would give even more detail,

I'm not aware of any problems with __pthread_unlock, and I've
tested it pretty extensively.  But maybe you have found a special
corner case where it fails?
