Hi Wanlong,

Case pthread_detach/4-3 fails with SIGSEGV randomly on x86_64 with 
Ubuntu 11.10.
I saw that you have made a patch for it. So would you like to give me 
some advice to solve it? Thanks.
It seems a multi-threads issue and I have try to debug with the core 
file but not much help.

The fail log:
