The following revision refers to this bug: https://chromium.googlesource.com/v8/v8.git/+/b8df95499338c86cf29bb8502a488a5ebf41c415 commit b8df95499338c86cf29bb8502a488a5ebf41c415 Author: bmeurer <bmeurer@chromium.org> Date: Tue Jan 31 08:30:55 2017 [turbofan] Don't eliminate unused CheckFloat64Hole. We cannot eliminate unused CheckFloat64Hole nodes, since loading from a holey array can have side-effects, i.e. triggering getters in the prototype chain.

Ouch, we are optimizing away {kCheckFloat64Hole} for some reason.
