Summary0002920: Crash under undetermined exact conditions
Descriptionnot sure what exactly is happening here, but I just got a bunch of crashes out of nowhere

there was a lot of wads loaded, and I did my best to narrow it down to two

'http://www.mediafire.com/file/cawkug8jxcz73ak/31337guns_131116.wad [^]' - of my own making

I didn't really do much testing because of relative lack of time, but if anybody asks me to do something I'll try my best

crashlog attached
Steps To ReproduceHost server, map TAT06
Shoot the switch in the very front of you until it opens a bunch of rooms to your side, releasing a bunch of imps and a lot of barons
Collect weapons and try to fight back
Eventually the server will completely crash

doesn't seem to be linked to any specific weapon or anything, I'm not 100% sure on this

 Some notes:

1)The DummyPlayer is spawned near the start area where Player 7 spot is present (coordinates -384,-1856);
2)The weapon RapidFireRL spawns missiles called MiniMissile2 which deal 0 damage according to their definition;
3)If an actor is hit by a missile dealing 0 damage, P_GiveBody is called.

So, the crash happens because of the DummyPlayer being hit by a MiniMissile2 fired by a player.

 The map is bugged, because real Player 7 spawn spot is swapped with its voodoo doll's spot. You can verify this in multiplayer offline mode by adding 7 bots and check the voodoo doll's spot (-576, 1600).

Still the crash is not good, but I wonder what's a good fix here.

 Please separate the new check from the existing checks. DummyPlayer is not a dead thing, so it follows a different logic. In the separate check, you won't need to check "actor->player != NULL" since COOP_GetVoodooDollDummyPlayer never returns NULL.

 Tested with r170122 and I couldn't get the crash to happen even after spamming the RapidFireRL on bots and other players. Seems the fix works without issue.
