last three frames:
1. http://github.com/spring/spring/blob/0.82.3/rts/System/Net/UnpackPacket.h#L49 [^]
2. http://github.com/spring/spring/blob/0.82.3/rts/Game/Game.cpp#L2824 [^]
3. http://github.com/spring/spring/blob/0.82.3/rts/System/SpringApp.cpp#L1037 [^]

while 2 and 3 match, i can not see the direct connection from 2 to 1.

possible problems for the crash:
* pckt == NULL || corrupted
* pckt->data == NULL || corrupted
* pckt->length has a wrong value

would be good if you could upload the demo for this game.

Actually I have seen quite a few NETMSG_PLAYERNAME throwing "Unpack failure (String)". This could be related, as I thought this would require network corruption or something and occur maybe a once a year.

this crash didn't happend (or wasn't reported) for over an year... so i guess its fixed.
