 The following code

    <?php
    class Test {
      function Test() {
        ob_start(
          array(
            $this, 'transform'
          )
        );
      }

      function transform($buffer) {
        return 'bar';
      }
    }

    $t = new Test;
    ?>
    foo

 outputs 'bar', as it is expected to do, with PHP 4.3.1.

 With PHP 4.3.2-RC and PHP 5.0.0-dev it outputs 'foo' which is just
 plain wrong.

Definitely related to bug #23466.

OG(active_ob_buffer).output_handler seems totally cluttered at the time php_end_ob_buffer() is called.

In 4 this is fixed now. The problem is still in 5. That is due to the problem that we have a different oo model in 5 (i guess).

I've tested this bug using the script seb wrote.

I've tested with PHP 4.2.2, 4.3.2RC2 and latest 4.3.2 snapshot (200305071630)

4.2.2 outputs:
Apache: bar
CGI: bar

4.3.2RC2 outputs:
Apache: bar
CLI: bar
CGI: foo

4.3.2 Snapshot outputs:
Apache: bar
CLI: bar
CGI: bar

Seems to be fixed in 4.3.2-Win32 now.

Its fixed in 5.0.0-dev so closing the report.
 [2003-05-07 15:43 UTC] davey@php.net 
sorry, I'm using Apache 1.3.27, with apache as SAPI not CGI, and WinXP without SP1. CGI tests were done from 'DOS'
