Crash dump

Git build: e307cc1a. Hard crash after pressing the first switch in valiant.wad MAP01. You can noclip right through the first door and up to the platform on the right to activate the switch, which results in a hard crash. Happens reliably. Crash dump is attached.

After debugging it, the problem has been reported in 

bool P_SetMobjState(AActor *mobj, statenum_t state, bool cl_update).

After checking Valiant MAP01 in Doom Builder, I noticed this happened because of a voodoo doll.

This happens because of the custom pinky in the closet. It looks like it's a dehacked parsing issue because the state it's attempting to set is an invalid number (1074) which overflows the state buffer which is size 1005.
