Opera and Chrome do not show this behaviour. Reproducible: Always Steps to Reproduce: 1. Create a setInterval call 2. Make the function have an expected argument defined 3. Add a createTextNode/appendChild call including that argument Actual Results: Random integers are written over the screen, mostly zero. Expected Results: The word undefined should be written repeatedly over the screen. This is the offending code: setInterval(function(t) { document.body.appendChild(document.createTextNode(t + ' ')); }, 0); More details at my blog post: http://azabani.com/45
