For one, you are testing to see if the contents of a class variable are equal to a class instance:
$TestObj->myself == $TestObj
Which seems a logic equivalent to: $TestObj->myself == TestClass() ???
And in your class you are setting a class variable equal to the class it is in:
$this->myself = $this
The recursion may actually be occurring in the $this->myself = $this line, but PHP isn't throwing an error until the comparison line.
Perhaps the comments posted in this link will help, it seems to explain the exact symptom you are getting:

Can someone tell me if I should fill a bug report about this or is it my fault???

This code:
<?php
class TestClass { public $myself;
function __construct () { $this->myself = $this; } }
$TestObj = new TestClass ();
if ( $TestObj->myself == $TestObj ) { echo "They are same.\n"; }
?>
Gives me a "Fatal error: Nesting level too deep - recursive dependency?"
on line #13: if ( $TestObj->myself == ...)
Could this be a PHP bug or I'm doing something wrong?
