Bug#46539 Various crashes on INSERT IGNORE SELECT + SELECT FOR UPDATE. If a transaction was rolled back inside InnoDB due to a deadlock or lock wait timeout, and the statement had IGNORE clause, the server could crash at the end of the statement or on shutdown. This was caused by the error handling infrastructure's attempt to ignore a non-ignorable error. When a transaction rollback request is raised, switch off current_select->no_error flag, so that the following error won't be ignored. Instead, we could add !thd->is_fatal_sub_stmt_error to my_message_sql(), but since in write_record() we switch off no_error, the same approach is used in thd_mark_transaction_to_rollback(). @todo: call thd_mark_transaction_to_rollback() from handler::print_error(), then we can easily make sure that the error reported by print_error is not ignored.
