Thank you for taking the time to report this bug and helping to make Ubuntu better.
Ubuntu does not ship libmysqlclient18 version 5.7.5-m15-1ubuntu14.04, so it seems to me that this is not a bug in Ubuntu. Instead you should report this bug with the party that provided that package to you. Since this isn't a bug in Ubuntu, I'm marking this bug as Invalid in Ubuntu for now. If you can reproduce the bug with Apache, MySQL and PHP packages that ship with Ubuntu, or otherwise can demonstrate that this bug is in something that Ubuntu shipped rather than with an external source, then please provide exact steps to reproduce and then change the bug status back to New. Thanks! ** Changed in: mysql-5.5 (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to mysql-5.5 in Ubuntu. https://bugs.launchpad.net/bugs/1495674 Title: libmysqlclient.so.18 segmentation fault on mysql_close_free_options To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.5/+bug/1495674/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
