Description

There is a known bug with Apache 1.3.x on Windows in which calling apache_get_modules() will cause Apache to crash. See http://bugs.php.net/bug.php?id=33292 .

The problem can be reproduced in a WAMP environment by attempting to modify the Permalink options, which causes got_mod_rewrite in admin-functions.php to be called.

Suggested resolution:

The problem can be resolved by adding the following code into got_mod_rewrite in admin-functions.php:

if ( function_exists('apache_get_modules') ) {

  if (preg_match("/apache\/1\.3.*\(win/i", $_SERVER['SERVER_SOFTWARE'])) {
    // Running Apache 1.3.x on Windows -- 
    // see bug http://bugs.php.net/bug.php?id=33292
    return true;
  }

  if ( !in_array('mod_rewrite', apache_get_modules()) )
    return false;
}

This checks for Apache 1.3.x running on Windows, and assumes that mod_rewrite is present. If this check were to return false, then save_mod_rewrite_rules() will not write to .htaccess, and the permalink structure cannot be updated.
