About:
The PCRE library is a set of functions that implement regular expression pattern matching using the same syntax and semantics as Perl 5, with just a few differences. PCRE is used by many programs, including Exim, Postfix, and PHP.

Release focus: Major feature enhancements

Changes:
An automatic callout feature can help with regex debugging. Patterns can be compiled and saved for later execution, even on different hosts, even when the endianness and/or pointer size is different. For a restricted set of patterns, partial matching is supported. General category Unicode character properties are optionally supported.

[»] what about the recursion bug affecting php (probably all apps using pcre)
by Mr.700 - Jan 11th 2005 04:52:34

Are bugs like RH bug #133891, PHP bug #24460, PHP bug #26171 and PHP bug #27070 going to be addressed?

In short: with some match patterns and data from 1000 bytes pcre causes php (and probably others) to crash. The problem seems to be that "PCRE uses recursion to handle subpatterns and indefinite repetition" (from PHP bug #24460).
