I just tried the latest development version (php5-200508221230) - here
it seems to work quite well, so the bug can be closed, as I can say.
Thanx!

Description:
------------
When calling debug_backtrace from an own error handler, it provides a
different output than when calling it directly. As you can see in the
code, I have two calls to debug_backtrace, one from my error handler,
the other from a function. As I raise an error shortly after calling
debug_backtrace the first time, I would expect to have the same first
few entries in the debug_backtrace array. I.e. the last entry shows an
error on line 18, where the function 'a_test' is called with arg
'another friend'. In real this function is called with the arg 'friend'
(arg 'another friend' is used in the next function call.
I hope I could explain the bug good enough as my natural language is
german. :-)
Reproduce code:
---------------
<pre>
<?php
function HandleError($n, $m, $f, $l){
print_r(debug_backtrace());
}
set_error_handler('HandleError');
function a_test($str)
{
echo "\nHi: $str";
b_test("another friend");
}
function b_test($str2)
{
echo "\nHi $str2";
print_r(debug_backtrace());
echo "now raise an error..".(2/0);
}
a_test('friend');
?>
</pre>
Expected result:
----------------
