We really need a reproducing script. Please try come up with one.

Like i said before, i can't track down the exact sequence (stacktrace
of the .php script code shows its in the 12-14th depth), and for full
debug - only after parsing about 15kloc of code.
When adding in debugging php source code in the new call (
$this->_helper = new helper($this);), it prevents the crash but in one
case a print_r($this) in the aggrevator:: scope resulted in an empty
object.
This testcase is more pseudocode of the segfault pattern than actual
instance. If you'd like I can privately attach the application source
- but again, its not an application problem - as turning off ze1_compat
doesn't cause a segfault , but is required for implicit clone.
This happens in the same spot for the 5.0.5, 5.0.6-dev and 5.0.6-latest
- even after building in seperate directories with no caching enabled.

This test case must not work at all.
$ php -d "zend.ze1_compatibility_mode=1" bug34712.php
Fatal error: Cannot use 'parent' as class name as it is reserved in
/home/dmitry/php/test/bug34712.php on line 20
Without "parent" it works fine on Linux/i386.
Try to make full rebuild.

Dmitry, you did something related to this lately?
------------------------------------------------------------------------
[2005-10-03 10:29:43] jason at jasonjustman dot com
last two lines of sample code should be:
$c = new child;
$a = new aggrevator($c);
