[2.2.13] Lua: Checking for P_PlayerInPain while in Match Mode causes a crash

Title says it all; if you try to check P_PlayerInPain while the Match gamemode is going on, the game instantly crashes when a player is spawned. Specifically I tested this on a multiplayer server; self-hosted games have this happen too (i.e. go to the multiplayer menu, start a server from match mode or switch to it, then enter the game). Unsure if it affects other multiplayer gamemodes besides match, all I know is that co-op is fine, and singleplayer works fine too.

Provided is a simple lua script that simply causes the crash immediately. And indeed, if you go in-game on anything else, this doesn't crash, and does print "a" whenever the player is currently in pain. match-test.lua

Oh, and here's a crash log:
