nodejs内存不足

Question

我今天遇到一个奇怪的问题。对于其他人来说，这可能是一个简单的答案，但这让我感到困惑。为什么下面的代码会导致内存错误？

var cur = 167772160;
var bcast = 184549375;
var addresses = [];
while (cur <= bcast){
  cur += 1;
  addresses.push(cur);
}
addresses.length 
addresses // memory goes from a few megs to over a gig in seconds when trying to print this

我得到了这两个错误之一…第一个是在节点的解释器中运行此代码时，第二个是通过nodeunit运行它时：

严重错误：CALL_AND_RETRY_2分配失败-内存不足

严重错误：JS分配失败-内存不足

Answer 1

当我尝试访问阵列时会发生这种情况。但是获取长度却没有。
