RangeError: Maximum call stack size exceeded on a seemingly simple file

[denik]

Parsing a file with a single variable declaration initialized to a big string causes RangeError to be raised.

var acorn = require("./acorn.js");
var fs = require("fs");
fs.readFile("./test/jquery-string.js", function(err, data) {
    if (err) throw err;
    acorn.parse(data);
});

master ~/work/acorn $ node test1.js 

/home/denis/work/acorn/acorn.js:804
        return finishToken(_string, String.fromCharCode.apply(null, rs_str));
                                                        ^

master ~/work/acorn $ node --version
v0.8.20

master ~/work/acorn $ git describe --tags 
v0.1-3-g782259b

Passing --stack-size=1000 to node seem to fix it, but esprima handles the file without any errors without any additional options, so I'm not sure if that's expected behavior or a bug.
