Would you mind trying the program below on your system? It may be
that on OpenBSD the pthread approach works for the main thread, and so
HAVE_LIBC_STACK_END isn't needed anyway.
(And interestingly, this program says that __libc_stack_end isn't
needed on my Debian GNU/Linux, despite the comment in threads.c
suggesting that it _is_ needed on Linux.)
Thanks,
Neil
#include <pthread.h>
int main ()
{
pthread_attr_t attr;
void *start, *end;
size_t size;
pthread_getattr_np (pthread_self (), &attr);
pthread_attr_getstack (&attr, &start, &size);
end = (char *)start + size;
printf("start = %p, &attr = %p, end = %p\n", start, &attr, end);
if ((void *)&attr < start || (void *)&attr >= end)
printf("__libc_stack_end is needed\n");
else
printf("__libc_stack_end is NOT needed\n");
exit (0);
}
