[cfe-dev] Building Clang/LLVM from Trunk with UnitTests On broken presently

[Reid Kleckner]

It's a known issue:
http://llvm.org/bugs/show_bug.cgi?id=13124#c15

I think you need to use a combination of building with clang, building
shared libs, enabling optimizations, and building the unit tests to trigger
this.
