Exception thrown from internals of Benchmark on simple example...

[getify]

I tried this simple example (node v7):

var Benchmark = require("benchmark");

Benchmark.options.onStart = function onStart(evt){
	console.log("onStart",evt.target.name);
};

var main = Benchmark.Suite("main");

main.add("test",function(){
	var x = new Array(1400);
});

main.run();

When I run this on the command line, the output I get is:

1. I'm not sure why onStart is getting called twice?
2. I don't understand why my usage is causing this exception?

Am I missing something?

Which version of Benchmark.js are you using?

[getify]

2.1.2

Narrowed the bug down to bb1511c. I have a patch. Going to test it a bit though.

[getify]

thanks for the update! glad i'm not crazy. :)

Anything I can do to help here?

[jdalton]

Naw. Not really happy with the fix so will be kicking it around a bit. It's getting to be that holiday time where I either have zero or tons of down time 😀

Can I safely apply this patch temporarily on my local install and move forward, or is it likely that the eventual fix will change behavior and I should just wait?

This patch is fine to apply. The second attempt will just refine and clarify some things.
