 Linux version 2.6.24-27-generic (buildd_at_crested) (gcc version 4.2.4
 (Ubuntu 4.2.4-1ubuntu3)) #1 SMP Fri Mar 12 00:52:19 UTC 2010
 x64

 intensive usage of boost::timed_mutex::scoped_lock from many threads with
 the same timed_mutex results in segmentation fault. Sample code is
 attached. It catches SIGSEGV signal in about 5-10 secs of normal operation
 and prints stack traces.

 Stack traces show:

 #5  <signal handler called>

 #6  0x00007f5834551244 in __lll_timedlock_wait () from
 /lib/libpthread.so.0

 #7  0x00007f583454d9ac in _L_timedlock_161 () from /lib/libpthread.so.0

 #8  0x00007f583454d230 in pthread_mutex_timedlock () from
 /lib/libpthread.so.0

 #9  0x000000000040a2f0 in thread_func ()
