    Description

      In sql/sql_class.cc, THD::cleanup() calls apc_target.destroy().

      The latter has:
      DBUG_ASSERT(!enabled) which fails during our test which triggers this code path.

      The fix is to disable apc_target if it is enabled before destroying it.

      Proposed patch:

      void THD::cleanup(void)
      {
      ...
        DBUG_ASSERT(!mdl_context.has_locks());
       
      +  if (apc_target.is_enabled())
      +    apc_target.disable();
        apc_target.destroy();
      ...
      }
