Hi Luke, I think this crash might be related with http://trac.webkit.org/changeset/96192 ... What do you think?

[Luke Macpherson]

Seems extremely unlikely to me that http://trac.webkit.org/changeset/96192 could have caused a bug. If those values were referenced anywhere before their new position it would cause a compile error.

[Martin Robinson]

Is this a flaky assertion failure or does it happen all the time?
