Summary: Invalid Trace File
Description:
In trace files, the same function number is shared between completely
different functions (ie. function number collusion). I suspect it is
related with handling of register_shutdown_function.

I can reproduce the situation with the following code:

<?php

function foo()
{
    echo "Hi";
}

function bar()
{
    echo "There";
}

register_shutdown_function("bar");

foo();

?>

The trace file output is:

Version: 2.0.2

                        0.005341 7044
TRACE END [2008-02-26 17:54:42]

as you see both "foo" and "bar" functions have function # of 2.

Thanks!
