Wireshark-dev: [Wireshark-dev] Crash when using adns on win32

I get a crash in the latest svn when using ADNS on win32 compiled with MSVC2005EE. In host_name_lookup_process() the adns_check() returns a adns_answer struct with some data in an union. The code using the data looks like this (line 2197):
 if (ans->status == adns_s_ok) {
   add_ipv4_name(almsg->ip4_addr, *ans->rrs.str);

In my debugger *ans->rrs.str is an invalid pointer, but ans->rrs.bytes points to a valid string. The invalid pointer causes wireshark to crash.
I do not get this crash using 0.99.8pre1 from the wireshark website.

Any ideas?
