Description:
------------
PHP is running as an Apache module. The following configuration was used to compile PHP:
./configure --with-apxs2=/usr/bin/apxs2 --enable-debug --disable-all

Test script:
---------------
1. Be sure browscap directive is commented out in php.ini
2. Set browscap setting in Apache configuration file, i.e. php_admin_value browscap "/some/path/browscap.ini"
3. Run the following PHP script:
<?php
ini_set('browscap', '/some/path/browscap.ini');
get_browser();

Expected result:
----------------
Notice or another type of message that indicates a misconfiguration (browscap directive is of the PHP_INI_SYSTEM type and can not be set/changed with ini_set() function or in Apache configuration file)

Actual result:
--------------
Program received signal SIGSEGV, Segmentation fault.
