Are you using pthreads? Signal handling with the threads is tricky. Is
SIG_IGN set before child threads are launched?
You should use the pthread interface to handle it.
int laststate, lasttype;
sigset_t sigs;
sigemptyset(&sigs);
sigaddset(&sigs, SIGPIPE);
pthread_sigmask(SIG_BLOCK, &sigs, NULL);
pthread_setcancelstate(PTHREAD_CANCEL_DISABLE, &laststate);
