test code to trigger the problem

glibc create stack space for per thread create by call pthread_create, but
the stack space willnot be freed, and cause program exhaust all virtual address
space then don't work anymore.
I attach the test code to trigger the problem
Comment 1 udknight 2013-03-29 05:42:05 UTC 
the stack does not get freed or reused even if the delay in creating threads is increased to up to 10 seconds
Comment 2 udknight 2013-03-29 08:47:13 UTC 
Sorry for my mistake, because the thread created by pthread_create is joinable,
and when a terminated joinable thread has been joined are the last of its resources  released  back  to the  system, so this is not a BUG.
