--- Comment #1 from Tom de Vries <vries at gcc dot gnu.org> ---
Reproduced again (with SLE-11 x86_64 -m64 PIE this time).

I've got no idea what's causing this.

We could add a non-null wstatus argument to the waitpid call and assert more
than just res != -1:
...
  res = waitpid (clone_pid, NULL, __WCLONE);
  assert (res != -1);
...

Also res, if not -1, should be the pid of the clone, so we could check for
that.

Also -1 in combination with EINTR is a valid result, and should be handled
appropriately.
