Bug report instructions are wrong

$ RUST_LOG=rustc=1 rustc lib.rs -L ../../rustsqlite/src/sqlite/
task 'rustc' failed at 'lookup_item: id not found: 108335', /home/jaymz/git/rust/src/librustc/metadata/decoder.rs:92
error: internal compiler error: unexpected failure
This message reflects a bug in the Rust compiler.
We would appreciate a bug report: https://github.com/mozilla/rust/wiki/HOWTO-submit-a-Rust-bug-report
note: the compiler hit an unexpected failure path. this is a bug
note: try running with RUST_LOG=rustc=1 to get further details and report the results to github.com/mozilla/rust/issues
task '<main>' failed at 'explicit failure', /home/jaymz/git/rust/src/librustc/lib.rs:453

The wiki link referred to does not exist and redirects to an edit page.

The RUST_LOG=rustc=1 environment setting doesn't appear to affect the error output.

The compiler error was caused by referencing an out-of-date compiled crate from a pre-0.9 compiler.

The same link also appears in this document: https://github.com/mozilla/rust/blob/master/CONTRIBUTING.md
Which is linked from the form for submitting new issues here on GitHub.

I added a page to the wiki with a link to the correct location, but the code should be changed. And yes, RUST_LOG=rustc=1 doesn't do anything in this case now.

I will fix that.

@JamesDunne Is the error itself something you wanted to report? If so, I would open up another issue for it.
