If the listed columns in the view definition of the table used in a 'INSERT .. SELECT ..' statement mismatched, a debug assertion would trigger in the cache invalidation code following the failing statement. Although the find_field_in_view() function correctly generated ER_BAD_FIELD_ERROR during setup_fields(), the error failed to propagate further than handle_select(). This patch fixes the issue by adding a check for the return value.
