I'm having problems when closing streams from another thread.

The following code:

static void *func(void *arg)
{
   fclose(stdout);
   fprintf(stderr,"Thread about to exit\n");
   return 0;
}

int main(int argc, char **argv)
{
   int thread_id;
   pthread_create(&thread_id,NULL,&func,NULL);
   pthread_join(thread_id,NULL);
   fprintf(stderr,"Process about to terminate\n");
   return 0;
}

Prints:

root@OpenWrt:/tmp# ./myapp_withmusl
Thread about to exit
Process about to terminate

But never returns! I have to send it a SIGINT.

This happens on target-mips_34kc_musl-1.1.11.

Thanks,
Nuno
