After updating from 4.04x to 4.05 i noticed a problem with regular expressions.

regular expression:

0-9a-zA-Z[:space:]\-\@\&\=\?\_\+\/\:\.\;

should normally find this:
http://p.moreover.com/cgi-local/page?index_humanrights+rss

using ereg(i) command - but no chance.

If I delete this: "-" (cgi-local to cgilocal) it works.

The regular expression worked with 4.04x and since updating it does not work any longer.

I think its a "critical" bug.

Interesting is that I have only probs with "-", but it seems to be that there are some more problems with another regular expression I had no time to analyze yet.

ok now the interesting part. As mentioned in the regex dox, "use - at the beginning or at the end.." it works.

So far, so good - but, the regular expression worked before without this (necessary) change.

Interesting point. After rewriting some of my sources now everything works again, sorry for bothering anyone.

Maybe it has something todo with my FreeBSD update from 4.2 to 4.3 (regex lib?) I don?t know.
