I'm having the same error. Funny part is that it is not always there, but once it is there, it won't go away until I restart the server. Issue is only in dev mode.

I'm not running on a GAE environment though. Only Apache 2.4, PHP 5.6 (with xdebug), MySQL 5.6, Symfony 2.3.6 / 2.3.7 / 2.4-beta2.

this is a separate error and it has to do with the php and libs the GAE devkit uses, it is just messed up
but in production it does not give any problems, probably one of the forbidden functions is used and then it messes things up and we end with cryptic errors, i am working on things for GAE

[2.3] Fix libxml_use_internal_errors and libxml_disable_entity_loader usage

This should fix #9731 and #9483 that seems to be triggered when `libxml_disable_entity_loader` has been called with `true` (see https://bugs.php.net/bug.php?id=62577)
As `libxml_disable_entity_loader` is non thread safe (see https://bugs.php.net/bug.php?id=64938) and as we have some calls that might leave the setting to `true`, I think the bug should be fixed.

I've checked the use of both `libxml_use_internal_errors` and `libxml_disable_entity_loader` among symfony code.

You can see I prefered to skip DomDocument::loadXML warnings using the `@` instead of using `LIBXML_NOERROR | LIBXML_NO_WARNING` because we can log these errors whereas libxml errors would be furtives.

 - [x] Check calls to DOMDocument::load
 - [x] Check calls to DOMDocument::loadXML
 - [x] Check calls to DOMDocument::loadHTML
 - [x] Check calls to DOMDocument::loadHTMLFile
 - [x] Add more tests
