Hi List!
I was reporting an access violation in the
Analyze->Statistics->Conversation List functions some while ago, but
noone could reproduce this bug.
The access violation is always at the same point while running it, but
is dependant on the capture file I have opened,
so it has to do something with the packets captured.
A capture file which is ok, is always ok, a capture file which fails
will always fail, so it's no transient bug :-)
The access violation is always in endpoint_talkers_tcpip.c line 51
(or the similar line in the other endpoint_talkers_xy sourcefiles,
depending on the function called):
add_ett_table_data(talkers, &tcphdr->ip_src, &tcphdr->ip_dst,
tcphdr->th_sport, tcphdr->th_dport, 1, pinfo->fd->pkt_len, SAT_NONE,
PT_TCP);
As the pinfo->fd is 0x15, the pinfo->fd->pkt_len is doing the access
violation.
The callstack is looking like this:
tcpip_talkers_packet(void * 0x021e1cb0, _packet_info * 0x021a3520,
_epan_dissect_t * 0x021a3518, void * 0x00c21880) line 51 + 10 bytes

Attached is a capture file which is causing this bug.
Could someone take a look at this, as I have not enough knowledge of the
conversation stuff to debug this myself.
