duplicate #47689 Previous Comments: ------------------------------------------------------------------------ [2009-07-03 11:03:53] David dot Gausmann at measx dot com Description: ------------ Hello, this Bugs seems to be similiar to http://bugs.php.net/bug.php?id=38512 My php version is 5.2.9 (because the current xampp version seems not to include a newer one). I've tried to replace the php files in the xampp installation, but it results in a crash. Please don't be angry that I've chosen a wrong php version here. I'm using PCRE to evaluate VBS source codes. To do this I use the current xampp version (1.7.1 / win32). During the evaluation process I've modified a regular expression. After that my browser told me "the server has reset the connection". As you can see the string (which shall be evaluated) is very long. I found out that error depends on three things: 1. The length of the evaluation string 2. The |"" in the pattern (which is wrong for VBS evaluation, but it was a test) 3. The "\'" in the evaluation string If the pattern whould be wrong then only a php error should occur. An other interesting fact is that the php script works fine if I execute the script with the php.exe directly. Hence the error depends on the combination apache - php - pcre I've already reported this bug to PCRE, but they said I should report it here. Kind Regards David Gausmann (Bananen-Joe) Reproduce code: --------------- $sContent = 'Call ABCDEFGHJIKLMNOPQRSTUVWXYZ("Lorem Ipsum dolor sit amet, consectetuer elitr\'" & VARIABLE & "\'" & vbCRLF & vbCRLF & "Lorem ipsum dolor sit amet conset" & vbCRLF & vbCRLF & "Lorem ipsum dolor sit amet consectetuer sadipscing.")'; echo preg_match('/^(?:[^"]|"(?:[^"]|"")*")*(?:var_alloc)\s*\(?\s*"[^"]+".*$/i', $sContent); Expected result: ---------------- preg_match should return 0 (no match) Actual result: -------------- The apache aborts the connection ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=48786&edit=1
