regex freezes on input

[mikelewis]

The following code hangs forever:

str="http://www.zerochan.net/868902********************************************************************"
PostRank::URI.extract(str)

I'm on Ruby 1.8.7.

I should say that there isn't even a hacky timeout workaround. This locks up all threads, which doesn't let me to timeout(3) { func }

:(

Hmm, interesting. It appears to hang on the regex match. Removing the \* from the valid_path_chars unblocks it, but that's obviously not the right solution: https://github.com/postrank-labs/postrank-uri/blob/master/lib/postrank-uri.rb#L47
