Well, except that bufptr is a pointing to an array of bytes which which means
that's fine. (Sorry, brain's apparently not working so well today.)
Must be that GDB is lying to me about where it cored because it makes more
sense that it cores in this macro (1 source line up from the previously
mentioned one):
#define NIB_WORD(n,b) \
(n) & 1 \
? (gint)((g_ntohl(*(guint32 *)((b) + (n)/2)) >> 12) & 0x0000FFFF) \
: g_ntohs(*(guint16 *)((b) + (n)/2))
Here it's trying to dereference a guint32 on a not-necessarily-aligned address.
I'm not going to attempt a fix now lest I just make things worse.
