[Bug linuxthreads/261] New: pthread_cond_timedwait_relative hangs

["jiten dot a at gmail dot com" <sourceware-bugzilla at sources dot redhat dot com>]

RedHat 7.3, glibc-2.2.5-34, kernel 2.4.18-3.

Following is a gdb trace, I get similar trace whenever my program hangs.

(gdb) where
#0  0x40ddf063 in __pthread_unlock () from /lib/i686/libpthread.so.0
#1  0x40dda25e in pthread_cond_timedwait_relative () from

#2  0x4024e04d in sr_waitsync () from /usr/dialogic/lib/libsrl.so

Base_Thread_Adapter.cpp:121
#9  0x40ddafef in pthread_start_thread () from /lib/i686/libpthread.so.0

ps awxr always returns pid of the thread in unlock. All other threads are trying
 to lock. Other application threads are running fine at this moment.

I have reproduced with a simple test code. How can I upload it?
