Create the following page: <meta http-equiv=refresh content=0.1> <style type="text/css"> .outer { -webkit-box-reflect:below 1px; } .inner { position:absolute; } </style> <div class="outer"><div class="inner"></div></div> Leave it running for a few seconds. Latest WebKit will crash. Tested on both PPC and Intel.
This doesn't crash for me - can you attach a crash log?
Created attachment 20949 [details] crash log
With guard malloc, I get a crash in RenderLayer::removeChild() when closing the page (even without the refresh).
