Calling the script below apache crashes on windows installations. After removing almost any of the lines inside $notworking apache will NOT crash, no matter which line was removed in most cases.


Here is the system list that causes a crash or not:

Windows 7 SP1 (64bit) | XAMPP | Apache/2.2.17 (Win32) | PHP 5.3.5 | <<<<<<< CRASH!
Windows XP (32+64bit) | XAMPP | Apache 2.2.17 | PHP 5.3.5 | <<<<<<< CRASH!
WinXP 32Bit / Apache 2.2.17 / PHP 5.2.14 <<<<<<< CRASH!
Fedora 32Bit / Apache 2.2.15 / PHP 5.3.3 --> OK
Ubuntu 10.10 32Bit / Apache2 2.2.16 / PHP 5.3.3 -> OK

Test script:
---------------
<?php
echo 'Is the following crashing apache or whatever?<br />'.PHP_EOL;

// After removing almost any of the lines inside $notworking apache will NOT crash, no matter which line was removed in most cases.

$notworking = '<?php

//<*IslandStorageBase:start*> DO NOT CHANGE THIS COMMENT!
/**
* Automatically generated BaseObject for IslandStorage. !!DO NOT CHANGE THIS BASE-CLASS!!
* CHANGES WILL BE OVERWRITTEN WHEN UPDATING!!
* You can change class "IslandStorage" which will extend this base-class.
*/
class IslandStorageBase extends AbstractSimpleStorage {
}
<*IslandStorageBase:end*>
?>';

$content = preg_replace(
  '%//<\*IslandStorageBase:start\*>(.)+<\*IslandStorageBase:end\*>%s',
  'test',
  $notworking
);

echo 'If you can see this everything seems to be working fine.';

?>

Expected result:
----------------
Is the following crashing apache or whatever?
If you can see this everything seems to be working fine.

Actual result:
--------------
Apache crashes with the following log entry:

Parent: child process exited with status xyz -- Restarting.
