Description Priit Laes 2009-08-31 17:52:14 UTC 
I'm getting hang (FUTEX_WAIT) in code using pthread_mutex_timedlock on i686 machines. On x86-64 
machine it works fine.

System: Gentoo
Glibc: 2.10.1
Kernel: 2.6.31-rc8
GCC: 4.4.1

strace output on 32-bit i686 machine
Comment 3 Ulrich Drepper 2009-08-31 18:03:29 UTC 
Reproduce it with the current code, not 2.10.1.
Comment 4 Priit Laes 2009-08-31 19:58:39 UTC 
Works with glibc master, marking WORKSFORME :)

PS. Could the "My Bugs" be changed so it would show bugs with WAITING status?
