Chrome Version: 62.0.3199.0 canary
OS: Chrome OS 9889.0.0

What steps will reproduce the problem?
(1) Load Cisco AnyConnect Chrome app on a nyan_blaze or veyron_minnie (both failed for me)
(2) Add connection
(3) "Initializing..." message never goes away

What is the expected result?

PNaCl module gets initialized and app runs normally.  (It works on x86 platforms, like samus and link.)

What happens instead?

In chrome://extensions I open the background page for the app, select Console, and see: "PnaclCoordinator: Compile stream init failed: reply not received from PNaCl translator (it probably crashed)"
