0002342: Server crashes after many players play, and many map changes in a hub.

Notes
(0012858) arkore (reporter) 2015-07-11 23:59	I forgot to say, repeat steps 2 and 3 a few times, over a time span of an hour.

(0013016) arkore (reporter) 2015-07-28 16:45	I did some work on the wads, and removed all my scripts (except the main one). It seemed like the server was running fine for a while, but then crashed. Now, things have gotten worse; I have no idea why. But now the server will crashed immediately on the first teleport-to-map done. 'http://static.painkiller.allfearthesentinel.net/logs/e00de618af5789d74322a267fce69b8e.txt [^]' It crashed the same way, today too. On the first teleport-to-map, to HUB. 'http://static.painkiller.allfearthesentinel.net/logs/c84a51c5861dc46133ed6010003a0486.txt [^]' Both have same error message: zandronum-server: /home/skulltag/BestBot/BuildStuff/zandronum-stable/src/p_sight.cpp:649: bool P_CheckSight(const AActor, const AActor, int): Assertion `t1 != __null' failed. Edward-san says this is a vexing bug. Nevertheless, this bug is having a huge impact on me. The server is crashing, and I have no idea why. What is P_CheckSight() anyways? Should I change my HUB map so that players start inside an empty (no items/actors in it) room (with a door) first? Or is P_CheckSight() still going to execute for player spawnpoint actors... This is the HUB map: 'https://www.dropbox.com/s/4nf3e70odq2iqwf/Screenshot%202015-07-28%2010.44.05.png?dl=0 [^]' A linedef with special action 74 is used for the "Teleport to Map" from another map to HUB map, or vice versa.

Edward-san says this is a vexing bug. Yeah, it happens when zandronum is built in Debug mode and with specific mods. I and the TSPG admins fixed this by building the server properly in Release mode. This should allow arkore to reproduce the crash again.

(0013022) arkore (reporter) 2015-07-30 15:28	I got the server to crash with new error message. Address not mapped to object (signal 11) Address: 0x8 'http://hastebin.com/iropimiseg.django [^]' 'http://static.painkiller.allfearthesentinel.net/logs/d1512367b8ae75bbc6630985ffe5d40a.txt [^]'
