When trying to expand a CanvasPixelArray data member of an ImageData object in the Scripts tab, the browser hogs memory and eventually freezes/crashes.
Issue present on at least BlackBerry Browser (BlackBerry PlayBook), Chromium 15 (Ubuntu), Chrome 17 (Windows XP).
The range of platforms suggests that it is javascript-engine independent (possible located in WebCore's bindings?) as Chrome uses v8 and the BlackBerry Browser uses JSC.
Reproduction steps:
1. Visit http://fooo.fr/~vjeux/epita/raytracer/raytracer.html#texturing
2. Inspect the Page
3. Navigate to Scripts
4. Apply breakpoint to trace.js:83 (Chrome seems to prefer :86)
5. Press "Ray Trace!"
6. When breakpoint is hit, add a watch expression for ctx.getImageData(0,0,this.width,this.height)
7. Expand the resultant ImageData
8. Attempt to expand 'data' the CanvasPixelArray member
