2Bug #69899: Segfault on stmt close after free_result with mysqlnd.
3--DESCRIPTION--
4The segfault happens only if the database connection was already closed and
5free_result is called on a prepared statement followed by closing that
6statement. This is due to mysqlnd_stmt::free_result (mysqlnd_ps.c) which
7unconditionally sets the connection of the statement to ready, despite the fact
8that it might already be closed.
