var_dump and print_r cause white screen

Question

My template is very simple:

get_header();
$new_p = get_posts(array('post_type' => 'post', 'numberposts' => 6));
get_footer();

whenever I put var_dump($new_p); or print_r($new_p); below $new_p = get_posts(array('post_type' => 'post', 'numberposts' => 6));, it gives me the white screen.

Why on Earth would it do it??

This code is OK, though:

var_dump(wp_get_recent_posts(array('post_type' => 'tdlrm_store_item', 'numberposts' => 8), OBJECT));

Any ideas?

Actually, memory was exhausted. Someone has copy-pasted an actual 2MB base64-encoded image into the post content, var_dump was trying to output it. Had to delete the image via PHPMyAdmin, because the WP editor won't open. Once it had been deleted, the problem was gone.
