It only occurs with .split("") and a mix of closures and intervals. Full script below: var str = "", ret, fn = []; for ( var i = 0; i < 16384; i++ ) str += "a"; for ( var i = 16384; i <= 131072; i *= 2 ) (function(i){ fn.push(function(){ ret = str.split(""); }); str += str; })(); window.onload = function(){ setInterval(function(){ if ( fn.length ) fn.shift()(); }, 13); }; 68473 1 mrowe 2008-01-28 12:35:55 -0800 After loading <http://ejohn.org/files/bugs/split/> the Caches window shows around 800,000 live objects, which is enough to trigger the "Out of Memory" error. Forcing a collection manually drops this down to around 270,000. Closing the tab drops back to around 8,000, which shows nothing is actually being leaked. 68474 2 mrowe 2008-01-28 12:38:07 -0800 <rdar://problem/5710766> 71628 3 ddkilzer 2008-02-23 13:27:24 -0800 Fixed by r30492? http://trac.webkit.org/projects/webkit/changeset/30492
