ID: 28875 Comment by: nospam at nihonbunka dot com Reported By: amoljak at cox dot net Status: No Feedback Bug Type: PCRE related Operating System: Windows 2000 Server PHP Version: 4.3.8-dev New Comment:
This seems very similar to the PCRE bug December 2003 No. 14 http://sourceforge.net/project/shownotes.php?release_id=469336&group_id=10194) "Bug fixes include: ... 14. A pattern such as /[ab]{1,3}+/ failed to compile, giving the error "internal error: code overflow...". This applied to any character class that was followed by a possessive quantifier." The above is essentially a "this is a solution" (not that I have solved it). Why is it not a good idea to post solutions? Is this bug tracker only to help cure the latest stable versions of php? There are many people using older versions, that want to know how to make the older versions of php work. It is with them in mind that I humbly submit this suggestion - to update PCRE. Thank you for php.

And are you aware that PCRE has certain limitations what it can handle and what not? ------------------------------------------------------------------------ [2004-06-22 18:06:38] amoljak at cox dot net Ok.. It crashes on two servers And on the third machine it gives the following warning: Warning: Compilation failed: internal error: code overflow at offset 72 in C:\work\servers\Apache2\htdocs\test\PHP\crashtest.php on line 7 (line 7 is the preg_match thing) But it does not crash. The php.ini options are the same. Thanks, Amol ------------------------------------------------------------------------ [2004-06-22 01:24:34] amoljak at cox dot net I tried PHP 4.3.8-dev and it is not crashing. So I am closing the bug. I will reopen if it occures on the machine I initially tried.
