Crash Data

See http://code.google.com/p/webm/issues/detail?id=136 for more details. We'll need to update libvpx or cherry pick this patch to fix crashes in this function on CPUs that support MMX but not SSE.
blocking2.0: --- → ?
Depends on: 577645
A new stable release of libvpx is due "later this month", we can pick this fix up when updating to that: https://groups.google.com/a/webmproject.org/group/codec-devel/msg/5b37d49297476888
Cherry picking that patch is tricky because there have been other changes to the file since we last updated. I'd prefer Tim took care of it if we're going to take this approach. Updating to the current git HEAD is going to need some work too. The status of our local patches against it are: reduce-warnings-1 OK splitmv-bounds FAIL subpixel-qword OK FUZZY subpixel-hidden FAIL emptyif_warning UPSTREAM solaris FAIL (minor, mostly OK FUZZY)
