When using libxml_use_internal_errors(true), and perform a possibly memory intensive operation like simplexml_load_string() next, you might end up with a blank screen and no php error logged because the error message been suppressed.

We use a custom error handler using set_error_handler() I found that after I call
libxml_use_internal_errors(false);
It resets my error_handler - not sure if this is a bug or not, I will report it as a bug - however, I needed to repeat my call to set_error_handler
(did confuse me for a while)
