Created attachment 68568 [details] crash log showing Thread 0 crashed, com.apple.JavaScriptCore Clicking on the "Zoom" icon runs some javascript to display the image in a slideshow view, but ends up crashing WebKit r68077. This does not affect Safari 5.0.2 (6533.18.5). 1. Visit URL 2. Click image, or Zoom icon --(This links to "http://www.flickr.com/photos/chris_leung/3533952785/sizes/l/", but runs some JS to show in a 'lightbox' slideshow on supported browsers, apparently) 3. Lightbox and image begins to load 4. WebKit crashes, sometimes hangs forever. Marked as Critical, as should fall under "crashes, loss of data, severe memory leak". The crash report showed "JavaScriptCore", so I filed it under there. I attached a screen recording showing comparison of WebKit and Safari, and the crash log.

Believe this is a duplicate of https://bugs.webkit.org/show_bug.cgi?id=46189 which was fixed in http://trac.webkit.org/changeset/68100. The current top of trunk build works fine with flikr.com. *** This bug has been marked as a duplicate of bug 46189 ***
