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 Bug#67564 may or may not be interesting additional reading on this subject.
