node 5.5: util.format on object crahes debugger

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.

#4819

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.

The fix is now in master, you should expect this to see it in a release in the next 2 - 3 weeks on v4 and v5.

thanks,
