ICE: translating unsupported cast (*const DST -> uint)

[arielb1]

The following code ICEs:

fn main() {
let r : &[int] = &[1,2,3];
let _ = r as *const [int] as uint;
}

with the following error:

error: internal compiler error: translating unsupported cast: *const [int] (cast_other) -> uint (cast_integral)
note: the compiler hit an unexpected failure path. this is a bug.
note: we would appreciate a bug report: http://doc.rust-lang.org/complement-bugreport.html
note: run with `RUST_BACKTRACE=1` for a backtrace

Ran into this too, I think, but the message is different in a static initializer:

extern crate libc;
fn main() {
    unsafe {
        static FOO: *const i8 = "foo\0" as *const str as *const i8;
        libc::puts(FOO);
    }
}

"impossible case reached: bad combination of types for cast"
