Description:
------------
I used a terinary operator to do a continue 0 or continue 2 
within a switch, and this caused PHP to seg fault... I am able to 
consitantly reproduce the bug. 

Reproduce code:
---------------
while( $value_array = each($this->tags) )
{
	$key = $value_array[0];
	$value = $value_array[1];
	$value['tag_id'] = $key;
			
	switch($tag_pos_type)
	{
		case "start":
			continue $value[3] == 1 ? 2: 0; //The problem
							
		case "end":
			continue $value[3] == 0 ? 2: 0; //The problem					
	}
			
	if( is_array($tag_type_array) )
	{
		if( in_array($value[0], $tag_type_array) )
		{
			return $value;
		}
	}
	else 
	{
		return $value;	
	}			
}

Expected result:
----------------
To either continue not at all, or to continue 2 

Actual result:
--------------
segmentation fault

This is really a logic error as well, as I should have done a 
continue 1 or continue 0 with a break, however I guess it 
should still be addressed because it does consitantly cash a 
seg fault.
