Now I had some time to investigate this.

It seems to me that llvm initializes some iostream thing, which calls
dynamic_cast<>() (at libstdc++-v3/include/bits/locale_classes.tcc:97), but the
unreal engine has its own implementation of that, or something with the same
name (in Core.so, unfortunately this is not included in the public unreal
sources), which takes precedence over libc++, and the world ends. Maybe it
wasn't a very good idea to use C++ in a GL implementation.

I also tried to run ut in wine 1.3.20, but the mouse is insanely fast, and the
mouse buttons jump the cursor instead of clicking. Running old things on linux
is really problematic :(
