Code: [Select]

    PLongArray = ^TLongArray;
    TlongArray = array[0..1] of longword;
var
   map : ^byte;
begin
   GetMem(map,256*256);
   PlongArray(map)[1] := $ffff; // -Mobjfpc : Error : Incompatible types : got "word" expected "TlongArray"
   FreeMem(map);
end.

AUTODEREF is active for Delphi and TP mode, for compatibility reason.
