I narrowed it down to ember-cli-uglify by disabling the addon in my ember-cli-build.js file, at which point builds would succeed.

ember-cli-build.js

module.exports = function(defaults) {
  let app = new EmberApp(defaults, {
    // ...
    'ember-cli-uglify': {
      uglify: {
        compress: false // added this to workaround the issue
      }
    },
    // ...

$ember --version --verbose

Note: I am having the same issues with terser. Fixing to 3.7.5 solves the issue. Still digging into the exact reason why.
