--- Comment #1 from duser at neet.fi ---
one more example that i forgot to add:

void fn()
{
        int *p;
        // Error: `p` is not of integral type, it is a `int*`
        // Error: `cast(int*)1` is not of integral type, it is a `int*`
        // works if parentheses around (p) are removed
        unsigned x = (unsigned)(p) & 1;
}

there's no ambiguous cast in this one so i've changed the issue title to
something that should apply to all the examples
