Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @alexcrichton (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. The way Github handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see CONTRIBUTING.md for more information.

I currently can't compile regex. See this comment for info: #50 (comment)

I get the same over here. I ran it under valgrind:

 valgrind rustc src/lib.rs --crate-name regex --crate-type lib -g -C metadata=64952606b89c7990 -C extra-filename=-64952606b89c7990 --out-dir /home/andrew/data/projects/rust/regex/target --emit=dep-info,link -L dependency=/home/andrew/data/projects/rust/regex/target -L dependency=/home/andrew/data/projects/rust/regex/target/deps

and got this: https://gist.github.com/087f0afda9e422cd44b1 --- bug in rustc? This is all the investigation I can do at the moment though. :-(

@alexcrichton ping. :-)

Hm, fascinating! Looks like rust-lang/rust#23032 has the segfault issue covered and the changes in #52 don't cause a segfault, so I'll merge that for now.

Thanks regardless!
