v8是否对单个对象的堆分配有限制？

a = new Array(1024*1024*102)

在节点命令行上失败

FATAL ERROR: JS Allocation failed - process out of memory

此外,当作为脚本运行时,这会失败并出现相同的错误

node --expose-gc --nouse-idle-notification --max-old-space-size=8192

FATAL ERROR: CALL_AND_RETRY_0 Allocation failed - process out of memory

var util = require('util');
o = {};

while(1) {
    o["hahahahahaha" + String(ctr)] = ctr;
    ctr++;

    if (ctr % 100000 === 0) {
        console.log(util.inspect(process.memoryUsage()));
        if (ctr % 10000000 === 0) gc();
    }
}

最后输出:

{ rss: 1009557504, heapTotal: 993408824, heapUsed: 964980592 }

然而,

var a = [];
while(1) {
    var …
