Make guard card in CardTable inaccessible

    XMLWordPrintable

Details

    • gc
    • b18

    Description

      `CardTable` reserves one extra card to detect overflow accesses, by checking whether that card holds a special value.

      An alternative could be make that extra card inaccessible (not commit) at all, which would catch the invalid access on the card table.
