delphi - 此代码是否由于编译器错误而无法构建？

Question

如果打开优化，使用 Delphi 6 时，构建(不仅仅是编译)会失败，并出现内部编译器错误。使用赋值代替 inc() 是有效的。这是编译器错误吗？奇怪的记录结构是因为原始代码已简化为这个最小的示例。

program Project1;

type
  requestCountsType = array[0..1] of
    record
    processed: int64;
    end;

  talliestype = record
    counts: requestCountsType;
    end;

  healthtype = record
    charged: talliestype;
    end;

procedure computeProcessed(const h: healthtype; var requests, bytesin, bytesout: int64);
var i: byte;
begin
requests := 0; bytesin := 0; bytesout := 0;
for i := 0 to 1 do
  begin
  inc(requests, h.charged.counts[i].processed); // including this generates compiler internal error C1405 when optimization is on
  // requests := requests + h.charged.counts[i].processed; // this works
  end;
end;

var ht: healthtype; var r, b1, b2: int64;

begin
computeProcessed(ht, r, b1, b2);
end.

参见bug report #109124 。我可以在Delphi XE中确认问题；错误报告说它已在 Delphi XE4 中修复。
