--- Comment #3 from Cody A. Taylor <cody.taylor at maternityneighborhood.com> ---
I closed with a test of a nightly build at http://trac.webkit.org/changeset/179912 and there was no crashes.

I tested again when https://support.apple.com/en-us/HT204560 (Safari 8.0.4, http://trac.webkit.org/changeset/180391) and the application again crashes. The following is the crashing thread.
