i can reproduce it.

the problem ist only existent, if

- i run php with normal php-sourcecode files
- i run php with eaccelerator with (eaccelerator-encoded) php-compiled files

the problem is not repuducable, if

- i run php with eaccelerator and normal php-sourcecode files

Do not file bugs when you have Zend extensions (zend_extension=)
loaded. Examples are Zend Optimizer, Zend Debugger, Turck MM Cache,
APC, Xdebug and ionCube loader.  These extensions often modify engine
behavior which is not related to PHP itself.

That's eAccelerator bug and it has nothing to do with PHP itself.

no, the problem occurs when i comment the loading of the extension in the php.ini!

with loaded extension, the bug doesn't occur. see my last comment.

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions. 

Thank you for your interest in PHP.

Unless you can demonstrate that the problem occurs with "stock' PHP without any extra extensions especially compiler related extnsion this is not a PHP bug.

the last time...the problem only occurs without any extensions.

i do not need any support, i'm reporting a bug.

We can't reproduce this behaviour without eAccelerator.
Please _check_ that you have not loaded any zend extensions (see `php -v` & phpinfo()).
