New Espruino - Testers Needed!

I have tried the DS18B20 example code which since the setInterval fix (1v59) has worked faultlessly:-

var ow = new OneWire(A1);
var sensor = require("DS18B20").connect(ow);
setInterval(function() {
  console.log(sensor.getTemp());
}, 1000);

However it now breaks after a couple of minutes with the following:-

ERROR: Out of Memory!
