On loading mods files smth goes wrong, server leaks all the memory and segfaults.
Tried on few mods, some have 100% reproducibility (RHS AFRF, ADR-97), some load normally, i.e. 0% (CBA).
Server reads mod's mod.cpp file, ignores its EOF, and tries to read data beyond. No data is read, but memory keeps being allocated until run out of memory.

Steps To Reproduce
- Install Arma 3 dedicated server (legacyports branch) using SteamCMD:
Steam> app_update 233780 -beta legacyPorts -betapassword Arma3LegacyPorts validate
- Run the server with mod(s); strace part is for more logging:
a) RHS AFRF
$ cd ~/Steam/steamapps/common/Arma\ 3\ Server $ strace -ff -o /mnt/memdisk/arma3server ./arma3server -netlog -ip=192.168.153.1 -port=2302 -cfg=/home/arma3server/Steam/steamapps/common/Arma\ 3\ Server/cfg/arma3-server-modded.network.cfg -config=/home/arma3server/Steam/steamapps/common/Arma\ 3\ Server/cfg/arma3-server-modded.server.cfg -mod=mods/@rhs_afrf4 -servermod=mods/@rhs_afrf4 -bepath= -loadmissiontomemory 4:20:08 SteamAPI initialization failed. Steam features wont's be accessible! $
b) ADR-97
$ cd ~/Steam/steamapps/common/Arma\ 3\ Server $ strace -ff -o /mnt/memdisk/arma3server ./arma3server -netlog -ip=192.168.153.1 -port=2302 -cfg=/home/arma3server/Steam/steamapps/common/Arma\ 3\ Server/cfg/arma3-server-modded.network.cfg -config=/home/arma3server/Steam/steamapps/common/Arma\ 3\ Server/cfg/arma3-server-modded.server.cfg -mod=mods/@ADR-97 -servermod=mods/@ADR-97 -bepath= -loadmissiontomemory 5:47:17 SteamAPI initialization failed. Steam features wont's be accessible! $
- Server crashes right after start (that is, in matter of seconds)
Additional Information
No rpt logs created by server: it crashes right after start, before writing any logs and only produces one line of output on console (see in steps to reproduce).
RHS AFRF version is latest from Steam Workshop (0.4.2).
Configs are modified examples from LGSM cfg.tgz. (~3 KiB) (server never reads them if crashed anyway)
