[PHP] debug_backtrace bug?

[Thomas Peri]

I wanted to run this past the list before submitting a bug report.  
(I've searched the bugs and haven't found anything relevant to my 
problem.)

The problem is that when s method of one class is overridden in a 
subclass, debug_backtrace() doesn't distinguish between the two 
methods.  For example, this code:

        class A {
                function __construct() {
                        $bt = debug_backtrace();
                        foreach ($bt as $t)
                                print $t['class']."::".$t['function']."<br>";
                }
        }
        
        class B extends A {
                function __construct() {
                        parent::__construct();
                }
        }
        
        $b = new B();
...produces this output:
        B::__construct
        B::__construct
...instead of the output I'd expect:
        A::__construct
        B::__construct
It happens for regular methods also, not just constructors.  Is this a 
bug, or is this behavior correct for some reason?  (Tested in php 
5.0.0, 5.0.1, and 5.0.2)

Thanks.
Thomas
