[Bug 298580] [NEW] Metacam segfaults on certain flash modes

[joseph]

Public bug reported:

Binary package hint: metacam

Metacam seems to segfault on certain Flash Modes (I'm using Canon 350d)

I downloaded source package and applied the ubuntu diffs to it and ran
through gdb. I found the following line seems to contain a problem
(dpyfuncs.cc: 435)

if (v[4]) {
	    static char *flashmodes[] = {
		"Auto", "On", "Red-Eye Reduction", "Slow Synchro",
		"Auto + Red-Eye Reduction", "On + Red-Eye Reduction"
	    };
	    cerr << "vp[4] = " << v[4] << endl;
	    if (v[4] <= 6)                 //<----- Should be < (not <=) as there are only 6 elements in flashmodes ?
		fmt(ctx, "Flash Mode", flashmodes[v[4]]);
	    else if (v[4] == 16)
		fmt(ctx, "Flash Mode", "External");
	} else

I think:
a)  dpyfuncs.cc:435 should read:   if(v[4] < 6)
or
b)  There should be another element in flashmodes

Please correct me if I'm wrong, or ask for more information.

Regards,
joseph
