--- Comment #1 from Tom de Vries <vries at gcc dot gnu.org> ---
This is a rewrite of abort-1.c that gets rid of the dg-shouldfail, by using
on_exit:
...
/* { dg-do run { target { ! openacc_host_selected } } } */

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>

static int trace;

static void
exit_handler (int status, void *arg)
{
  if (trace != 1)
    abort ();

  if (status != EXIT_FAILURE)
    abort ();

  _exit (0);
}

int
main (void)
{
  trace = 0;

  on_exit (exit_handler, NULL);
  trace++;

#pragma acc parallel
  {
    abort ();
  }
  trace++;

  return 0;
}

/* { dg-output "libgomp: " } */
...
