Yes. It is that function that cases the crash rasmus.
Compiling php-5.4 from current SVN the tests run just fine :)

Can you try reproducing with the current svn code?
I went through the reproduce steps and the unit tests ran to completion for me.
However, under Valgrind I did get some complaints for one of the tests. Can you
tell if your crash is on this same test?

Stas, this looks like a blocker for 5.4

Description:
------------
First off: Sorry not being able to provide a better reproduce. I tried to dig
into symfony but failed as I'm not familiar with it. I was testing phpunit
against frameworks when I found this.
Running the symfony 2 test suite with RC6 leads to a segfault that I had across
two machines so I'll open this just in case it helps out and ask sf people to
maybe provide a better reproduce.
PHP Configure: Configure Command => './configure' '--enable-mbstring'
'--with-readline' '--enable-pcntl' '--with-zlib' '--prefix=/opt/php-5.4.0RC6/'
'--enable-debug'
Test script:
---------------
git clone git://github.com/symfony/symfony.git
cd symfony
./vendors.php
/opt/php-5.4.0RC6/bin/php `which phpunit` --debug --filter FormLoginTest
Expected result:
----------------
No segfault
Actual result:
--------------
