I am using CVS from August 12, compiled with Zend2, as a   
module in Apache 1.3.23. My problem is this: When I use a   
class constant as the default value to an argument in a   
function, the first time I call the function (omitting the   
argument), PHP correctly uses the value of the constant   
for the value of the omitted argument. The second time I   
call the same function (again omitting the argument), PHP   
uses a slightly-garbled form of the name of the class   
constant, instead of the value of the constant. For   
example:   
  
<?   
class FooBar {   
	const BIFF = 3;   
}   
   
function foo($biff = FooBar::BIFF) {   
	echo $biff . "\n";   
}   
   
foo();   
foo();   
?>   
  
The expected output of this is (obviously):   
3   
3   
  
The output I get is:   
3   
foobar :BIFF  
  
(The space before ":BIFF" should be a non-printing  
character, rendered as a box on my system, but I'm not  
sure if it will come through properly :)  
  
This error does not occur when using regular "define()'d"  
constants. For example, if I replaced FooBar::BIFF with a  
constant BIFF, I get the expected output (no garbled  
constant names, "3" is displayed by each call to foo()).
