--- Comment #4 from Michael Saboff <msaboff at apple.com> ---
I suspect that this is fixed by the change to <https://bugs.webkit.org/show_bug.cgi?id=143727> - "DFG register fillSpeculate*() functions should validate incoming spill format is compatible with requested fill format" which was landed in change set r182827: <http://trac.webkit.org/changeset/182827>.

It is hard to prove if we can't reproduce the crash.
