internal compiler error: self wasn't mapped to a def?!

[indutny]

This error happens when trying to access self within local/embedded function:

struct A;
impl A {
  fn m(&self) {
    fn x() {
      self.m()
    }
  }
}

When I attempt to replicate the bug, I get the following output from rustc:

% ./x86_64-apple-darwin/stage2/bin/rustc -v

The ICE is indeed disturbing, but the earlier error indicates that something is awry in the code.

When I changed the code by replacing the fn x() { ... } with let x = || { ... }, the code seems to compile fine...

(not closing since we should still try to stamp out the ICE.)

Just ran into this myself. Confirming.
