The current Linux SteamCMD executable always segfaults when quitting.

Steps to reproduce:

1. get a clean SteamCMD installation (from tarball)
2. run it so it can update itself
3. stumble upon the following output:
   Loading Steam API...Process $PID failed to shm_open /steam-ValveIPCSharedObjects5
4. type quit when the Steam> prompt appears
5. get a segmentation fault

This happens on an up-to-date Debian Jessie.
