Hey Richard,
I have another one for you. I'm seeing the following assert:
Assertion failed: ((E->isGLValue() || E->getType()->isFunctionType() || E->getType()->isVoidType() || isa<CXXTemporaryObjectExpr>(E)) && "can't evaluate expression as an lvalue"), function EvaluateLValue, file /Users/mcrosier/llvm-clean/llvm/tools/clang/lib/AST/ExprConstant.cpp,
line 913.
