Is this a bug? Adding the class var field changes prints 0 and
without it prints 100 as expected. The class var is just a static
field that isn't actually part of the record so how could it affect
the memory layout?
A class var is (as the name suggest "not instance") not part of the
instance. (instead a scoped global var).
So a pointer to the instance can not be to the memory that holds the
class var data.
Sorry, strike above / messed up the field names while reading. You
aren't accessing "z".
My bad.
type
TMyRec = record
class var z: UInt32;
x, y: UInt32;
end;
var
r: TMyRec;
p: pointer;
begin
r.x := 100;
p := @r;
writeln(PUInt32(p)^);
end.
