System: NetBSD sheep 8.99.24 NetBSD 8.99.24 (SHEEPKMS) #4: Sat Aug 11 11:29:18 CEST 2018 onno@sheep:/usr/src/sys/arch/i386/compile/SHEEPKMS i386

>Description:
Run program below compiled with cc -pthread whatever.c and
the before and after messages are printed
Run program below compiled with cc -pg -pthread whatever.c and
only the before message is printed.
Using -static as an extra option gives the same results.
#include <pthread.h>
#include <unistd.h>
void *dowait(void *arg) { sleep(1); pthread_exit(NULL); }
int main(void)
{
pthread_t pthid;
if (pthread_create(&pthid, NULL, dowait, NULL) == 0) {
write(1,"before join\n", 12);
pthread_join(pthid, NULL);
write(1,"after join\n", 11);
}
}
>How-To-Repeat:
Run test progam compiled with and without -pg
>Fix:
No idea what the influence of -pg is and if this is a lib category PR.
