Comment # 5 on bug 76484 from Nicolai Hähnle

Judging by the backtraces, the game overrides the C++ operator delete in a way
that gets confused with LLVM (which is also a C++ library) and then crashes.
Probably it's a game bug.

Your best bet for working around this problem is to link LLVM statically (i.e.
convince the LLVM build to statically link against libstdc++, and then
statically link LLVM into Mesa).
