node 5.5: util.format on object crahes debugger

[thomas-mindruptive]

node 5.5, windows 8.1

Following code crashes the debugger (it exits the app on "util.format" without an error message).

var util = require("util");
var obj = { 1: "fasdadsaas", 2: "safsdafdsafsadfad" };
var message = util.format("Format the object: %O", obj);
var i = 1;

Reproducible through "node debug formatBug.js", as well as node-inspector and Visual Studio Code.

For us it's quite severe because we are logging to the console extensively during development. "console.log" uses "util.format" and therefore crashes the debugger.

Thanks

@mindruptive I have a patch in that should fix this although we are just trying to get a working test for it. I'm hoping I can get this working today.

Thanks a lot for the fast response.

P.S.: For the moment, I'm using following work around: I'm replacing the various "console.log" functions by my own. They simply tunnel/send the log statements to a chrome browser through web sockets. That's good enough for the moment and makes the log output easily readable.
