Column aggregation works fine, but not in symfony project. After some self investigatings i did'n found something, that should cause segmentation faults. Maybe that's because I didn't understand well the core of doctrine internals.

I thought, that I have problem with php-5.2.0 on debian etch, later with php-5.2.3 on lenny, but I also compile php-5.2.5 myself, but segfault still occures.

I'll assume, you already have some symofny project with sfDoctrinePlugin and database configured correctly.

Here is simple schema.yml you will need to generate test models:

$ cat config/doctrine/schema.yml
Entity:
  tableName: node
  columns:
    name:
      type: varchar
      size: 20
    # used for column aggregation
    type:
      type: integer
      size: 11

User:
  inheritance:
    extends:  Entity
    keyField: type
    keyValue: 1

Group:
  inheritance:
    extends:  Entity
    keyField: type
    keyValue: 2

$ symfony doctrine-build-model
>> doctrine  Generated models successfully

Now there are three generated models - Entity, User, Group in lib/models/doctrine/generated. The base class for User looks like this:

abstract class BaseUser extends Entity
{
  public function setTableDefinition()
  {
    parent::setTableDefinition();
  }

  public function setUp()
  {
    parent::setUp();
    $this->setInheritanceMap(array('type' => '1'));
  }
}

This is fine, and inheritance should work, but without Column agregation. If I select from Entity, I do not have User and Group instances in collection, but instances of Entity

For working column aggregation I need to define child classes to parent class via subclasses method.

So I edit user model in lib/models/doctrine/Entity.class.php to look like this:

class Entity extends BaseEntity
{
  public function setTableDefinition()
  {
    parent::setTableDefinition();

    $this->setSubclasses(array(
      'User' => array('type'=> 1),
      'Group' => array('type'=>2),
    ));
  }
}

Now in some action try to create your first record (symfony module yourapp yourmodule;cd apps/yourapp/modules/yourmodule).

$ cat actions/actions.class.php
class testActions extends sfActions
{
  public function executeIndex()
  {
    $user = new User();
    $user->name = 'adrive';
    $user->save();
  }
}

Now when you execute your action you will find in your apache error log notice about segfault

$ tail /var/log/apache2/error.log
...
[Mon Dec 17 16:29:43 2007] [notice] child pid 14609 exit signal Segmentation fault (11)

I try this on latest sfDoctrine (6540) with Doctrine (3279) and PHP versions mentioned above PHP 5.2.0-8+etch7, PHP 5.2.3-1+b1 (Lenny), and custom PHP 5.2.5 on Lenny.
