Dmitry, with the provided script I can reproduce this.

http://www.jasonjustman.com/crash.phps
line 114 is what causes the segfault:
$this->_transform_actions = new
base_object_meta_transform_actions($this);
its not clean nor tight, but an example of the pattern that causes it
to crash

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.
