regex-tdfa issue with large regexps

Hi and thanks again Christopher.. I just used regex-tdfa for the first time. I'm looking for a native haskell regex lib that's installable and reliable on all platforms. Perl-style regexps would be ideal. I know regex-tdfa doesn't support these (yet ?) but it did install easily on windows which is promising. I noticed it's quite sensitive to regexp size; it will eat all ram on my 1G mac with regexps larger than 500 chars or so. With pcre-light, I could get up to about 32K before a runtime error. Is there an issue tracker for the regex packages ? Best, -Simon
