 code:

 {{{

 add_action('pre_get_posts', function($query) {
     // when is on page
     get_page_template();
 });

 }}}

 breaks WP core in
 "Allowed memory size of 134217728 bytes exhausted" in wp-includes\class-
 wp-query.php

 steps:
 1. Add upper action to functions.php
 2. Enter to any WP page
 3. Fatal ERROR

 It breaks WP in each function:
 get_single_template()
 get_category_template()
 get_post_type_archive_template()
 get_taxonomy_template()
 get_archive_template()
 get_home_template()

 when function is fired in 'pre_get_posts' hook and this is current WP
 page.
