New Comment:
zend_alter_ini_entry_ex has several failure paths. It would be helpful to know
which one is being triggered. Can you investigate this? You can try first by
starting apache under gdb with the -X option.

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.
