Bug #75869 [NEW]: Lack of isolation on mysqli_driver->report_mode

From: xavier dot leune at gmail dot com Operating system: Ubuntu 17.04 PHP version: 7.2.1 Package: MySQLi related Bug Type: Bug Bug description:Lack of isolation on mysqli_driver->report_mode Description: ------------ Hi there, When changing the report_mode of an instance of mysqli_driver, all instances (already created or future instances) will share the same value of report_mode. This can be very annoying when a 3rd party library enables the exceptions on mysqli, if some other 3rd party library makes the assumption that the report_mode is to it's default value. Thanks, Xavier.
