Description:
------------
If include_path wasn't set already, setting it to some concatenation of ${include_path} causes a segfault.

Seems different from #37002, AFAICT

More details in Debian bug : http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=497453

Reproduce code:
---------------
For instance, if /etc/php5/apache2/php.ini doesn't contain any include_path definition, like is by default in Debian :
 ; UNIX: "/path1:/path2"
 ;include_path = ".:/usr/share/php"

then setting the following in for instance /etc/php5/conf.d/zend.ini :
 [Zend]
 include_path = ${include_path} ":/usr/share/php/libzend-framework-php"

leads to segmentation fault.


Expected result:
----------------
I guess referencing variables no yet explicitely set, but having default values should return their default value.

Uncommenting the default include_path in /etc/php5/apache2/php.ini allows it to work.


Actual result:
--------------
Apache segmentation fault

Hi.

Sorry, but I'm afraid I won't have time to test that at the moment.

Should be testable by anyone interested still.

Best regards,

Ignored until requested feedback is given.

Noticed this bug on my system (PHP-5.2.10/Linux), seems only to exist in apaches mod_php. Having include_path = ${include_path} ":/usr/share/php/libzend-framework-php" in zend.ini but no setting in php.ini causes apache not to start at all. 

This does not seem to affect php-cli.
