Hi!

I'm forwarding this from <https://bugs.php.net/bug.php?id=70309>;
apparently it has been overlooked to report it to the libxml2
maintainers so far.

TL;DR: there is some unwrapped debug output in
xmlTextReaderValidatePush() which may be triggered if RelaxNG validation
is requested:
<https://github.com/GNOME/libxml2/blob/2c8dc7158a3b7b028454abcb6f162c4da28ed80b/xmlreader.c#L989>.
 The printf() should probably be wrapped in an #ifdef DEBUG_READER or such.

Regards,
