I've submitted this as a bug (similar to #62554 listed in
compiler\delphi\code generation\optimization, but not fixed in Delphi 5). A
workaround is to declare the array as const.
Cheers,

Subject: [DUG]: Array of variant: problems
I have a function that takes an array of variant constructed at runtime, but
if the resultant array length is zero I get insurmountable problems. A
simple example:
procedure Execute(A: array of variant);
begin
ShowMessage('Exiting...');
Exit;
ShowMessage(A[0]); // This never runs, but ANY reference causes problems
end;
procedure TForm1.Button1Click(Sender: TObject);
begin
Execute([1]); // Works
Execute([]); // Sometimes "invalid variant operation",
// sometimes access violation in oleaut32.dll
// (depending on what other code is around)
end;
Can anyone tell me why?
Cheers,
Carl
