Receiving error on simple script

[steebchen]

I created a test on jsperf, but it shows an error, but not in my script:

Uncaught TypeError: Cannot read property 'name' of undefined.
  message: Uncaught TypeError: Cannot read property 'name' of undefined
  fileName: http://jsperf.com/benchmark-47.js
  lineNumber: 21

What is wrong with my test?

I had this too recently when testing NodeListJS ticket 4. eorroe had this to say:

Seems to be a jsperf problem
when you debug it, its doing:

(R = T.createElement(U)).name = S;

T.createElement(U) returns a div and then it trys to get the property name which is undefiend

Looks like you may possibly be having the same problem as #44. Sorry I don't have more info at the moment.

Doesn't seem to effect the tests? I'm getting the same error on Chrome

What is this strange jsperf.com bug? It does not happen on every test case... but at mine: http://jsperf.com/replace-xpath-vs-text

JSPerf seems to want to run a piece of Java code! In the benchmark-47.js file, at line 1978 there is a ui.js reference, and in here looks like it's trying to load nano.jar.

By default my Chrome does not run Java code.

Looking at it, it looks like a shim for Opera Mini, but it's breaking Chrome. In Firefox I noticed that it asked me to also run this Java, and I got a very similar error (although it has P[0] as the reference).
