 This code does not work in PHP 5.0.5:
 {{{
 $post = get_post( wp_insert_post( ... ) );
 }}}

 You get: Fatal error: Only variables can be passed by reference in wp-
 admin/includes/post.php on line 379

 According to the PHP 5 changelog, this was fixed in 5.1.0: "Allowed return
 by reference from internal functions. (Marcus, Andi, Dmitry)". Related
 (per my search; not referenced in the changelog):
 http://bugs.php.net/bug.php?id=34468,
 http://bugs.php.net/bug.php?id=34424.

 I have not tested this on 4.4 but I have not been able to find a mention
 that this was fixed in the 4.4 branch. Generally our PHP 4 testing is on
 4.3, hence why this was missed.

 This was discovered as Earthlink uses 5.0.5 (release date 05-Sep-2005).
 Committing the fix, assigning first to a local variable as we do
 elsewhere, for 3.0.1, and recommending to Earthlink they upgrade to at
 least 5.2.
