The following C code fails to compile.

struct S {
    float f;
};

struct S2 {
    double d;
};

Error: `tupleof` is not a member of `const(S)`
Error: invalid `foreach` aggregate `_error_`
Error: `tupleof` is not a member of `const(S2)`
Error: invalid `foreach` aggregate `_error_`

Note that the error messages do not have source location either!
