构建,而不仅仅是编译,如果使用Delphi 6,如果优化是打开的,以下内容会失败,内部编译错误.使用赋值而不是inc()工作.这是编译器的错误吗？奇怪的记录结构是因为原始代码已经减少到这个最小的例子.
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,b2);
end.
解决方法
见
bug report #109124.我可以在Delphi XE中确认问题;该bug报告说在Delphi XE4中已经修复了.
