New Comment:
Unable to reproduce with 5.5.3 or 5.6.0-dev on Debian 7 or OSX using PHP CLI
(unable to test with Apache at present).
Piotr do you get the same results using the CLI? What other modules do you have
loaded?
A backtrace of the coredump might also be useful.

Description:
------------
Call to @list on an array returned by function_get_args() will incorrectly fill
variables (only last one is filled) 80% of the time and will cause a
Segmentation fault (11) on the other 20%.
PHP 5.5.3 run on Apache 2.2.22
Test script:
---------------
function a() {
$opts = func_get_args();
@list($a, $b, $c) = $opts;
var_dump($a, $b, $c);
}
a('1','22', '333');
Expected result:
----------------
string '1' (length=1)
string '22' (length=2)
string '333' (length=3)
Actual result:
--------------
null
null
string '333' (length=3)
Or segfault:
[Tue Sep 10 10:57:46 2013] [notice] child pid 32315 exit signal Segmentation
fault (11), possible coredump in /etc/apache2
