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, Christoph M.
