This is still broken. Any update?

I haven't had time to look at it yet. Hopefully soon. It's probably a bug in the parser somewhere.

This is a nasty bug. I probably won't fix it tonight. Basically, character class negation is completely broken when the class contains two or more non-overlapping ranges. The current code will match if any range matches, but when the class is negated, this should be switched to no ranges matching. I'm probably going to do this by simply inverting ranges (otherwise I'd need to invent a new VM instruction that knows how to "and" things).

@BurntSushi so, @alexcrichton fixed up mal's implementation to work with rust nightly (kanaka/mal#26) which included fixing up rust-pcre (https://github.com/alexcrichton/rust-pcre) to work with nightly. The priority of fixing this bug in regex is probably not as urgent (at least, not for me).
