We had a protection against it, by allowing versioned delete if: trx->id != table->vers_start_id() For replace this check fails: replace calls ha_delete_row(record[2]), but table->vers_start_id() returns the value from record[0], which is irrelevant. The same problem hits Field::is_max, which may have checked the wrong record. Fix: * Refactor Field::is_max to optionally accept a pointer as an argument. * Refactor vers_start_id and vers_end_id to always accept a pointer to the record. there is a difference with is_max is that is_max accepts the pointer to the field data, rather than to the record. Method val_int() would be too effortful to refactor to accept the argument, so instead the value in record is fetched directly, like it is done in Field_longlong.
