iExploder test #13774 causes an assertion failure in debug builds of ToT WebKit. This is the same assertion failure as Bug 14714, but has a different test case.
* STEPS TO REPRODUCE
1. Launch Safari/WebKit.
2. Open test case.
This does not occur on the Safari 3.0 (522.12) public beta with its original WebKit on Mac OS X 10.4.10 (8R218).
Tested with a local debug build of WebKit r24513 with Safari 3.0 (522.12) on Mac OS X 10.4.10 (8R218).

Reduced test case
As I commented in http://bugs.webkit.org/show_bug.cgi?id=14714, Hyatt has mentioned that he would really like to pull our current implementation of column layout before Leopard ships. I wonder if that is how he will want to fix this bug. Looking into it in the meantime anyway.
Fixed with r24599...same as http://bugs.webkit.org/show_bug.cgi?id=14714
