Asserting reduced test case

The attached test case, reduced from a boost::statechart test, causes the
following assertion:

caj at nyanko:~/clang-temp$ clang++ t.cc -w
clang: CodeGenFunction.h:1366: void
clang::CodeGen::CodeGenFunction::EmitCallArgs(clang::CodeGen::CallArgList&,
const T*, clang::ConstExprIterator, clang::ConstExprIterator) [with T =
clang::FunctionProtoType]: Assertion
`getContext().getCanonicalType(ArgType.getNonReferenceType()). getTypePtr() ==
getContext().getCanonicalType(Arg->getType()).getTypePtr() && "type mismatch in
call argument!"' failed.
