BZ #12310: pthread_exit in static app. segfaults
Static applications that call pthread_exit on the main thread segfault. This is because after a thread terminates __libc_start_main decrements __nptl_nthreads which is only defined in pthread_create. Therefore the right solution is to add a requirement to pthread_create from pthread_exit. ~~~ nptl/ 2013-06-24 Vladimir Nikulichev <v.nikulichev@gmail.com> [BZ #12310] * pthread_exit.c: Add reference to pthread_create.
