Comment 51 for bug 856072

jchen points out that it could be strlen(domain) that fails, and that the domain pointer is extracted from a structure returned by a function internal to the NetBSD resolver code (__res_get_state()), which we haven't copied. If this is where the problem originates -- due to incompatible layout of struct _res_state, or some such -- we're going to have to pull in res_state.c, and perhaps more (if we also need to replace res_ninit()). Does someone who can reproduce the crashes want to check this hypothesis before we dive further into it?
