Hello. I don't really know what llvm.org is, or what to do with a crash
backtrace, preprocessed source, or associated run script. However, the error I
received while trying to compile Unreal Engine 4 for Linux did compel me to
submit a bug report with all of the aforementioned items attached, so I will
attempt do so to the best of my abilities.

Hope this is found useful.

I also try to compile the UnrealEngine under Linux (Arch Linux). Using Clang
3.7 and it crashes. Help! https://wiki.unrealengine.com/Building_On_Linux

Terminal output: http://pastebin.com/HtVKHd85
/tmp/Module-e4f7d1.sh: http://pastebin.com/aZf4Jkt8
/tmp/Module-e4f7d1.cpp file is waaaay too big to upload.

Ah, I found out I should not use clang 3.7! Only 3.5 and 3.6 are supported according this wiki https://wiki.unrealengine.com/Building_On_Linux

You can use agetpkg to get older packages in Arch. So install clang 3.5 or 2.6 incl. llvm and llvm-libs packages of the same version.
