Description:
------------
5.4 and trunk segfaults running the testsuite:
http://ci.qa.php.net/view/php-userland/job/php-symfony2/75/label=debian-
amd64,phpversion=5.4/console
http://ci.qa.php.net/view/php-userland/job/php-symfony2/75/label=debian-
amd64,phpversion=trunk/console
while 5.3 runs the suite successfully:
http://ci.qa.php.net/view/php-userland/job/php-symfony2/75/label=debian-
amd64,phpversion=5.3/console
I rerun the command with --debug for phpunit, and the last test before the 
segfault is 
Symfony\Tests\Bridge\Doctrine\Form\Type\EntityTypeTest::testSubmitMultipleExpand
ed.
I rerun the test only for that test 
class(Symfony\Tests\Bridge\Doctrine\Form\Type\EntityTypeTest), and it is 
passing, no segfault.
The segfault also goes away, if I use --process-isolation for phpunit (will run 
each test in a separate process, instead of running them in the same process 
that is running phpunit), so it seems that there is no single snippet to 
reproduce the error.

here is the backtrace from the coredump that I got:
