Description Berend-Jan Wever 2010-02-04 02:07:38 PST 
Repro:

<BODY></BODY>
<SCRIPT>
  document.designMode = "on";
  document.execCommand("selectall");
  document.execCommand("InsertLineBreak");
  document.execCommand("InsertLineBreak");
  document.execCommand("forecolor", false, 1); // Optional, see note
  document.execCommand("InsertText", false, 1);
  document.execCommand("SelectAll");
  document.execCommand("createlink", false, 1);
  document.execCommand("justifycenter", false);
</SCRIPT>

The "forecolor" line is optional: there are two different crashes that can 
happen, one with it and one without (latest non-debug build of Chromium):

WebCore::Node::shadowAncestorNode ReadAV@NULL 
(3b90161564d80c611251f74d8780bd91)
WebCore::CSSStyleDeclaration::diff ReadAV@NULL 
(2b02a76b8ac89beb9292332299f74c09)

Both repro's trigger ASSERTs in debug builds. Details and repros are attached to the chromium bug:
