From http://code.google.com/p/chromium/issues/detail?id=70228: Chromium 10.0.642.0 (71590) What steps will reproduce the problem? 1. Navigate to some page (e.g. google.com) 2. In the same tab, navigate to other page (e.g. yandex.ru) 3. Open DevTools, open CPU profiles page, start profiling. 4. Press the "Back" button in browser. Expected: tab navigates back to the page from item 1., profiling continues. Actual: tab renderer crashes.
