Hello Igor, I'm looking at the buildbot http://buildbot.askmonty.org/buildbot/grid?category=main&branch=bb-10.2-mdev9543 and I see that your push https://github.com/MariaDB/server/commit/0c6d753708dfe07607ab6879b4832fe6ec5... causes failures for win.test with --ps-protocol: http://buildbot.askmonty.org/buildbot/builders/kvm-fulltest2/builds/4911/ste... Question #1: can you fix this? Question #2: Also, stacktrace printing is broken in the tree: mysqld: /home/buildbot/buildbot/build/mariadb-10.2.0/sql/set_var.cc:1205: sys_var::where get_sys_var_value_origin(void*): Assertion `!mysqld_server_started' failed. Fatal signal 6 while backtracing Could a failure like this be caused by "the backport" that was pushed earlier?
