<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>When generating a fallback `post_name` using the post ID, `wp_insert_post()` should clear the post cache immediately.
If the post cache is not cleared at this point, the cache can become stale
for operations performed before the cache is cleared later in the function.
Specifically, the generation of a `guid` for new posts can use stale data,
resulting in non-unique values. <a href="https://core.trac.wordpress.org/changeset/33262">[33262]</a> introduced a call to `get_post()`
that introduced just such an invalidation problem.
Fixes <a href="https://core.trac.wordpress.org/ticket/5305">#5305</a>.</pre>
