Reduced test case. It seems this bug is quite complicated, it requires two
semantic errors, plus uniform function call syntax, and a template constraint:

template template6385(T)
{
    enum template6385 = false;
}

void bug6385(A)(A a) if (template6385!A)
{
    this_is_an_error();
}

const bool bool6385 =
    is(typeof(
    {
        ubyte[2] r;
        this_is_another_error();
        r.bug6385;
    }()
    ));

The test case was accidentally fixed by commit:
https://github.com/D-Programming-Language/dmd/commit/dc83c
but I don't really understand why. It seems to be just luck.
