Yes, it is a bug.  In fact LLVM from subversion from a few days ago
crashes even without -march=cpp:

$ llc test.bc
llc: llvm/include/llvm/Support/Casting.h:202: typename llvm::cast_retty<To, 
From>::ret_type llvm::cast(const Y&) [with X = llvm::MDNode, Y = llvm::Value*]: 
Assertion `isa<X>(Val) && "cast<Ty>() argument of incompatible type!"' failed.

Please open a bugreport at http://llvm.org/bugs

Ciao,
