FATAL error with pthread_cancel in multi-thread program

[cs-wang]

while the main thread send cancel signal with pthread_cancel(child_pid), and the child thread set cancel state enable with pthread_setcancelstate(PTHREAD_CANCEL_ENABLE, &oldstate); the program will aborted abnormally with core dumped.
glog version is glog-0.3.3
