Yep: The crash is in the memcpy near line 3640 in packet-cip.c (obtained from a
gdb backtrace with a tshark built with -O0).
#0 0x00c4b553 in dissect_cip_generic_service_rsp (tvb=0x8c308c0,
pinfo=0xbff5d4a4, tree=0xb787e888) at packet-cip.c:3640
Totally garbage pointers in struct
(gdb) p *preq_info
$13 = {dissector = 0xbaddcafe, bService = 254 '\376', IOILen = 3135097598, pIOI
= 0xbaddcafe, pData = 0xbaddcafe, ciaData = 0xbaddcafe}
{
memcpy(&req_data, preq_info->ciaData, sizeof(cip_simple_request_info_t));
}
