Got Result:
Doing bar as foo ...
Array
(
[bar] => Array
(
[methods] => Array
(
[0] => doit
)
[properties] => Array
(
)
)
)
Doing bar as foo ...
i know the get_class() returns wrong classname on second hit, as it
returns 'foo' instead of 'foobar'.
Expected result should be:
Doing bar as foo ...
Doing bar as foobar ...
Clear enough for you, sniper, buddy? (sorry about this taunt)

Not enough info (as in: what was the expected result, etc..etc..)

The bug is not fixed. Run the following script either before or after
applying andrei's recent patch, one will reproduct the bug.
<?php
class bar {
function doit()
{
print "Doing bar as " . get_class($this) . " ...\n";
}
}
class foo {
function foo()
{
print_r(aggregation_info($this));
aggregate($this, "bar");
}
}
class foobar extends foo {
}
$a = new foo();
$a->doit();
unset($a);
$b = new foobar();
$b->doit();
?>

This bug has been fixed in CVS.
In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.
In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
Thank you for the report, and for helping us make PHP better.

This short script can reproduce the aggregation bug I reported above.
class bar {
function doit()
{
print " Doing...\n";
}
}
class foo {
function foo()
{
print_r(aggregation_info($this));
aggregate($this, "bar");
}
function spawn()
{
return new foo();
}
}
$a = new foo();
$a->doit();
$b = $a->spawn();
$b->doit();
unset($a);
$c = $b->spawn();
$c->doit();
Besides 'unset($a)', '$a = new foo()' will also cause the same problem.

Similar problem happens to me. I either cannot reproduce the
situation because sometimes changing a irrelevant place will temporaily
wipe the problem away. But it will come back at an unexpected time.
The problem once caused Apache 2.0 crashing on Win32. But after some
irrelevant code restructuring, it now casues
error like this:
Fatal error: Call to undefined function: foo() in /path/bar.php on line
xxx
But foo() is surely an aggregated method. The strange but perhaps
useful point is that a print_r of aggregation_info() at the bug place
shows the function dose exists. Even I add the following codes the
error still exists:
if (!method_exists($this, "foo")) {
deaggregate($this, "CLASS_having_method_foo");
aggregate($this, "CLASS_having_method_foo");
}
This problem really stops me from doing any futher coding.
I tried ZendSafeGard, upgraded to the 4.3.2RC2, changed from Apache
module to CGI, and moved from Windows to Linux(RedHat 9.0). But none
seems to imporve the situation.
Since the problem is not easily reproduced outside my complex class
hierarchy, please instruct me of any other debug information I can
print out at the bug place. And because the PHP I'm using is
recompiled, I would even like to try do source codes debugging.
