I can reproduce this,
#0 0x401afd80 in __pthread_sigsuspend () from /lib/libpthread.so.0
#1 0x401aea7c in __pthread_wait_for_restart_signal () from
#2 0x401afc40 in pthread_create@@GLIBC_2.1 () from /lib/libpthread.so.0
Seems like it's waiting for some signal to be passed to the process, but
it doesn't happen.
