Bug #61415 [NEW]: zend_alter_ini_entry failuers

From: Operating system: Linux PHP version: 5.3.10 Package: Safe Mode/open_basedir Bug Type: Bug Bug description:zend_alter_ini_entry failuers Description: ------------ I wrote an apache2.2 module that changs open_basedir and php_includepath dynamically into translatename hook with zend_alter_ini_entry. This works perfectly but for about 5% of requests i get a PHP Warning with a wrong open_basedir. From my debug logs i get a FAILURE on zend_alter_ini_entry("open_basedir",...) with the rate of about 5 requests over 100; this never happen for 'includepath' ini entry. For any call to zend_alter_ini_entry i submit always the same string for each virtualhost, i can't understand why the function output change without a input values change.
