 New Comment:

I'm using 5.5.30 and php-fpm and can reproduce the problem by using the inverse of the script:

Test script:
---------------
<?php

die(var_dump(libxml_disable_entity_loader(true)));

---------------

The default seems to be false for me. After a few hits the results all end up true, so somehow this
value is persisting within php-fpm children.

Also fixed in 5.5.22 (per the commits above).

Any suggested workarounds for this issue? This bug is pretty critical because it can basically take
down sites running something like Magento. It appears to only be fixed in PHP 5.6, which a lot of
codebases aren't ready for yet.

Sorry, but I would like to ask for clarification:
For php-cgi I see the following behaviour:
1. I issue a request that has a call of libxml_disable_entity_loader()
2. A subsequent request to a different script that is NOT calling libxml_disable_entity_loader is
affected by the first request because the setting is shared between subsequent requests on the same
process.

Is this a bug or working as intended?

PHP 5.4.39 with libxml 2.9.2
