Failed get in util::ppaux::re_scope_id_to_str, followed by ICE #2586
Description
Gist of the backtrace: https://gist.github.com/2926927
This came up because I had set RUST_LOG=rustc::middle::typeck::infer=3 in order to debug an unrelated issue in infer, and turning logging on for infer caused this.

the problem here is the synthesized expressions created for predicates in the type check fn
check_constraints(). they don't have a real expression id so there is no corresponding entry in the ast_map. this is pretty sketchy code to begin with, so I guess I'd be inclined to change that code rather than the print-out.nikomatsakis commentedon Jun 16, 2012
on the other hand, that'd be hard. so maybe I'll just make the printouts not fail when they find something unexpected but instead print out a less-than-useful string.

or maybe take the VERY EASY path and remove the preconditions from
core::result::iter2paper over #2586 by not failing when the key is not found

Fixed in commit 41a21f0, which removed current incarnation of typestate.
