the update step should be "k = k >> 1", otherwise "k >= 1" will never become
false and a low memory condition will lead to an endless loop.

No, I think it is fine as it is, because 1/2 = 0.5 < 1

   try {
-    closure();
-    assertUnreachable();
+    ab = new ArrayBuffer(maxSize * k);
   } catch (e) {
-    error = e;
+    ab = null;
   }

+assertTrue(ab != null);
 
-  // We expect custom formatting to be lazy. Setting the custom
-  // function right before calling error.stack should be fine.
-  Error.prepareStackTrace = function(e, frames) {
-    return "bar";
