Product: clang
Version: trunk

This is the return of bug 10592. The new testcase is:
struct Helper {
unsigned long id() { return 0; }
};
void test(Helper *obj) {
int i = static_cast<const unsigned long&>(obj->id());
}
which triggers this assertion in codegen:
nlewycky@ducttape:~/local/delta-2006.08.03$ clang -cc1 -emit-llvm-only -x c++
-w z.c
clang: CGExpr.cpp:2296: clang::CodeGen::LValue
clang::CodeGen::CodeGenFunction::EmitCallExprLValue(const clang::CallExpr*):
Assertion `E->getCallReturnType()->isReferenceType() && "Can't have a scalar
return unless the return type is a " "reference type!"' failed.
