Bad method resolution on pointers

[philberty]

I tried this code:

extern "rust-intrinsic" {
    pub fn offset<T>(dst: *const T, offset: isize) -> *const T;
}

#[lang = "const_ptr"]
impl<T> *const T {
    pub const unsafe fn offset(self, count: isize) -> *const T {
        unsafe { offset(self, count) }
    }

    pub const unsafe fn add(self, count: usize) -> Self {
        unsafe { self.offset(count as isize) }
    }
}

I expected to see this happen: compile without error

Instead, this happened:

test.rs:12:18: error: expected [* const T=T REF: 33] got [& * const T=T REF: 33]
    8 |         unsafe { offset(self, count) }
      |                         ~
......
   12 |         unsafe { self.offset(count as isize) }
      |                  ^

The location info looks pretty wrong here as well which does not help.
