| Script is typescript, started Wed Oct 31 08:09:42 1990
| rpp386-> cat abort.c
| #include <signal.h>
| #include <assert.h>
| #include <stdio.h>
| 
| main (argc, argv)
| int	argc;
| char	**argv;
| {
| 	signal (SIGIOT, SIG_IGN);
| 	assert (argc == 2);
| 	printf ("hi dave!\n");
| }
| rpp386-> cc -o abort abort.c
| abort.c
| rpp386-> ./abort
| Assertion failed: expr, file abort.c, line 10
| hi dave!
| rpp386-> exit
| Script done Wed Oct 31 08:10:00 1990
