On OSX 10.7, neither Safari, Chrome, nor a ToT build of WebKit crash for me... Created attachment 105095 [details]
System Profiler report from affected machine
(In reply to comment #2) > On OSX 10.7, neither Safari, Chrome, nor a ToT build of WebKit crash for me... It crashes 100% of the time on the Lion laptop I have in the office running 10.7.1. Attached the System Profiler report from this machine. I'm sure it isn't machine specific because Gregg Tavares reported the same problem on his laptop. See http://crbug.com/92590 . Thanks Ken, the system profile helped. It appears only certain configs of physical cores vs. virtual cores hits the bug so it's unlikely that it affects many machines. We may just have to avoid using this fast path until the bug is fixed, or perhaps just leave it. I'm not sure how to easily work around the issue at the moment. |
