compiling libstd with -Z extra-debug-info results in "intrinsics.rs:402:8: 402:38 warning: debuginfo: Could not find namespace node for function. This is a bug! ..."

On Ubuntu 12.04/amd64, gcc 4.7.2, when I'm trying to build rust with -Z debug-info on stage1 and -Z extra-debug-info on stage2, libstd will not compile, and possibly points out a compiler bug if the error message is to be believed.

This appears to have been fixed in the meantime. We have a very large number of debug info tests, so I think we're safe closing this.
