[Nut-upsdev] newhidups with APC Smart-UPS 1500

The source of the segmentation fault is in newhidups.c at line 534.
528
529 void upsdrv_updateinfo(void)
530 {
531 hid_info_t *item;
532 char *nutvalue;
533 int retcode, evtCount = 0;
534 HIDItem *eventsList[10];
535
536 upsdebugx(1, "upsdrv_updateinfo...");
537
538
The array only holds pointers to 10 HID items.
> =>Got 16 HID Objects...
Produces a segmentation fault.
I got around this by temporarily increasing the size of the array.
HIDItem *eventsList[32];
A better fix is needed. The code loops until the total number HID objects are retrieved. The array needs to hold this total number of HID objects in all cases to avoid problems.

Thanks. This is useful info, but not sufficient to isolate the bug.
Could you run newhidups in the debugger, like this:
gdb drivers/newhidups
(gdb) run -DDDDD -u root auto
[the driver will run and produce enormous amounts of debugging output, then crash. Then issue the following command to generate a backtrace, which, with some luck, will tell us exactly where the program crashed. ]
(gdb) bt
Please send both the debugging output before the crash, and the debugger output after it. Feel free to play around with additional debugger commands.
If the resulting file is too large to post on the mailing list, you can (exceptionally) send it to my address directly. But in general, please keep the traffic on the mailing list. Thanks, -- Peter
