When NULL is passed as argument `pthread_create(&id, NULL, run, (void *)&args)` , the test is failing with an exit value 139. To solve that i have included the functions `pthread_attr_setdetachstate` , `pthread_attr_setguardsize` and `pthread_attr_setstacksize` to set attributes for the thread. 
Commenting `pthread_attr_setdetachstate` and `pthread_attr_setguardsize` the test has passed. I will update it here.

Thank you @tstuefe
