>Description:
Calling pthread_exit() from only (main) thread
does not cause process to exit.
>How-To-Repeat:
#include <pthread.h>
int main(int argc, char** argv)
{
pthread_exit( NULL );
/* not reachable */
return -2;
}
cc -o threadtest threadtest.c -pthread
./threadtest; echo $status
Process will not exit until interrupted/killed.
Top(1) shows process in 'select'.
>Fix:
Woraround: Keep track of number of active threads and
have last thread exit with exit() instead of phtread_exit().
