If you do change a tab then close, you get a huge leak: LEAK: 2537 Node LEAK: 3 RenderObject LEAK: 1 Frame LEAK: 14055 KJS::Node 11598 2 dev+webkit 2007-04-30 16:07:40 -0700 Oh, and there's no assertions failing with this. Maciej said on IRC he's seeing an assertion failure at frame 0 of my stack trace above running the layout tests so I figure I'd mention that. 11043 3 darin 2007-05-04 22:19:13 -0700 <rdar://problem/5183692> 10769 4 ddkilzer 2007-05-07 15:07:33 -0700 Here is another way to reproduce this (with a slightly different stack trace). I'm using a local debug build of WebKit r21288 with Safari 2.0.4 (419.3) on Mac OS X 10.4.9 (8P135): *STEPS TO REPRODUCE 1. Open Safari/WebKit. 2. Go to: http://www.ssh.com/ 3. Go to: http://www.google.com/ [this site apparently doesn't matter] 4. Hit browser back button to return to www.ssh.com. 5. Quit Safari.
