backtrace of clang crashing

Hi,
the attached preprocessed source (unreduced) crashes with
clang: /home/corni/clang/llvm/include/llvm/Support/Casting.h:200: typename
llvm::cast_retty<To, From>::ret_type llvm::cast(const Y&) [with X =
clang::VarDecl, Y = const clang::NamedDecl*]: Assertion `isa<X>(Val) &&
"cast<Ty>() argument of incompatible type!"' failed.
and the attached backtrace.
