This function will continue forever if given an <type>array</type>
or <type>object</type>
that contains a direct or indirect reference to itself or that
contains an <type>array</type> or <type>object</type> on a deeper
level that does so.
This is especially &true; for <literal>print_r($GLOBALS)</literal>,
as <literal>$GLOBALS</literal> is itself a global variable and
contains a reference to itself as such.
