 A memory exhaustion occurs given the following snippet of code:

 {{{#!php
 <?php
 add_action( 'admin_enqueue_scripts', function() {
         wp_set_script_translations( 'wp-i18n', '' );
 } );
 }}}


 {{{
 <b>Fatal error</b>:  Allowed memory size of 268435456 bytes exhausted
 (tried to allocate 262144 bytes) in <b>/srv/www/editor/htdocs/wp-
 includes/class.wp-dependencies.php</b> on line <b>324</b><br />
 }}}


 Memory exhaustion occurs here:

 https://github.com/WordPress/WordPress/blob/4e3e9ca9cf893190609728848caf224034fd1ef0
 /wp-includes/class.wp-dependencies.php#L338

 I think it stems from this line:

 https://github.com/WordPress/WordPress/blob/4e3e9ca9cf893190609728848caf224034fd1ef0
 /wp-includes/class.wp-scripts.php#L517

 Where `wp-i18n` is adding itself as a dependency.

 Could probably do for a simple check to ensure that the incoming handle is
 not `wp-i18n`.
