Operating system: FreeBSD 6.2-RELEASE-p1
PHP version: 5.2.3
PHP Bug Type: PCRE related
Bug description: Pattern causing crash
Description:
------------
This problem showed up after an upgrade to php 5.2.3 that was accompanied
by a pcre upgrade to ver 7.0. It works fine on my local system (php 5.2.3,
pcre 6.7)
The browser returns a download dialog rather than an error.
If I remove the "=" from the pattern, it works, but doesn't find
anything.
Reproduce code:
---------------
<?php
$s =
"((?is-U)<input(?:(?:\s*\w*\s*(?:=(?:(?:'.*?')|(?:\".*?\")|(?:\w*)))?)*)(?:>|(?:\/>)))";
$formHTML = "Nothing to see here:<input name='blah' value=''></input>";
echo preg_replace("/" . $s . "/is", "muffin", $formHTML);
?>
Expected result:
----------------
I would expect this code to replace the input tag string with "muffin". I
would also expect it not to crash.
Actual result:
--------------
Download dialog box.
