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