Hi Vinson
This patch looks remarkably similar to the one I've sent a few weeks ago
- with yours having a lot better commit message :)
The way I see it (after a subtle hint from calim) this patch improves
the issue from "accessing undefined variable/array(ptr)" to
"array out of bounds" - sample_index must be zero but the caller can
choose a different value.
IMHO the most suitable approach would be to provide undefined data to
the caller (same as what the intel code does), like show below.
case 8: ptr = ms8; break;
+#ifndef NDEBUG
assert(0);
break;
+#else
+ return;
+#endif
Cheers
Emil
