How does 'the other system' protect against this?

Release date of function1?

I took a look into the B&V source, and it seems the following change may
help. It will show a message box about the problem, and not add the function
to the function list.

(FastcodeChallengeUnit.pas, line 117, 118)

uses
UtilsUnit, Windows, Dialogs;

(FastcodeChallengeUnit.pas, line 237-)

function TFastcodeChallenge.RegisterFunction(const FunctionData:
TFastcodeChallengeFunction): PFastcodeChallengeFunction;
var
i: Integer;
begin
// -- Added check for duplicates
for i := 0 to Pred(FFunctionList.Count) do
begin
if CompareText(PFastcodeChallengeFunction(FFunctionList[i]).Name,
FunctionData.Name) = 0 then
begin
ShowMessage('Duplicate function name: ' + FunctionData.Name +
#13#10 + 'Not added to function list!');
Exit;
end;
if (PFastcodeChallengeFunction(FFunctionList[i]).Addr =
FunctionData.Addr) then
begin
ShowMessage('The same function is used under different names: ' +
#13#10 +
FunctionData.Name + #13#10 +
PFastcodeChallengeFunction(FFunctionList[i]).Name +
#13#10 + 'Not added to function list!');
Exit;
end;
end;
// --- end of added code
New(Result);
try
Result^ := FunctionData;
FFunctionList.Add(Result);
except
Dispose(Result);
raise;
end;
end;
