Does this result in a segfault? * Run with opcache.optimization_level=0. Does this fix the issue? ------------------------------------------------------------------------ [2019-10-06 19:26:07] shaun at shaunfreeman dot name Description: ------------ I have come across a bug when OPcache is enabled. I am using Ubuntu 18.04 and PHP 7.3.10. When OPcache is enabled then mysql_xdevapi\CollectionFind::limit and mysql_xdevapi\CollectionFind::offset return bool instead of an mysql_xdevapi\CollectionFind instance. When OPcache is not loaded then I get the expected result.
