Log file of crashed Painkiller: Hell and Damnation run

Overview: 
    The game "Painkiller: Hell and Damnation" randomly crashes (segfaults)
in-game, probably due to a LLVM-related bug.

Steps to reproduce:
    1) Install the Painkiller: Hell and Damnation Linux client (resource:
http://store.steampowered.com/app/214870/)
    2) Start the game, enter a level
    3) Play until it crashes

Actual results:
    A random crash 2-3 minutes into playtime.

Expected results:
    No crash.

Build date and platform:
    Build date of all components: 12/02/2013
    Linux kernel version: 3.12.1-gentoo x86_64
    Mesa: git (c4cf487315f1f5375534f1677177983fa496d577)
    LLVM: 3.5-svn (bc134cb1f18e6870ccebbf03e40b7de11f274644)

Additional information:
    The error log, including a backtrace, is attached. It strongly suggests the
problem is related to LLVM.
    There is no demo client available for Painkiller: Hell and Damnation, I
will attempt to reproduce this bug in other programs (like Xonotic).
