This is not just a stacktrace problem. If you were to attempt use
'$this' in funcB you would find that '$this' is actually available and
is an instance of class testA.

I stumbled on this accidentally.

<?php

class testA
{
    public function funcA()
    {
        testB::funcB();
    }
}

class testB
{
    public function funcB()
    {
        echo get_class($this);
    }
}
    
$obj = new testA();
$obj->funcA();

?>

Expected result:
----------------
nothing

Actual result:
--------------
testA

It appears as though the static method is being executed in the context
of the calling object. Strange behaviour.

Description:
------------
When calling a static function from inside of a class the backtrace /
stacktrace reports the call as a normal object call, i.e. its showing
->, where it really should show ::

Reproduce code:
---------------
<?php

        class testA
    {
        public function funcA()
        {
                testB::funcB();
                }
    }


        class testB
    {
        public function funcB()
        {
                echo "<pre>";
                debug_print_backtrace();
                echo "</pre>";
        }
    }
    
    $obj = new testA();
    $obj->funcA();

?>

Expected result:
----------------
#0  testB::funcB() called at [/home/site3/public_html/t1.php:7]
#1  testA->funcA() called at [/home/site3/public_html/t1.php:23]



Actual result:
--------------
#0  testB->funcB() called at [/home/site3/public_html/t1.php:7]
#1  testA->funcA() called at [/home/site3/public_html/t1.php:23]
