Got a local retrace which is better:
--- stack trace ---
#0 0x00000000004044d8 in process_dev (devname=0x0) at hdparm.c:1826
fd = 3
err = 52

multcount = 0
id = 0x0

Thread 1 (Thread 3074):

1821: }
1822: }
1823: if (get_apmmode) {
1824: id = get_identify_data(fd, id);
1825: printf(" APM_level = ");
1826: if((id[83] & 0xc008) == 0x4008) {
1827: if (id[86] & 0x0008)
1828: printf("%u\n", id[91] & 0xff);
1829: else
1830: printf("off\n");
1831: } else

2394: while (argc--) {
2395: argp = *argv++;
2396: if (no_more_flags || argp[0] != '-') {
2397: if (!num_flags_processed)
2398: do_defaults = 1;
2399: process_dev(argp);
2400: continue;
2401: }
2402: if (0 == strcmp(argp, "--")) {
2403: no_more_flags = 1;
2404: continue;
So clearly id == NULL here, and id[83] crashes.
