Angular 5 код, скомпилированный в режиме производства, дает void 0, а не ошибку функции

Работает нормально в режиме dev.

Ошибка:

Uncaught TypeError: (void 0) is not a function

Код bundle.js, где возникает ошибка:

webpackJsonp([1], {
    ....
    wi = new yi.l("UseV4Plurals"), Ei = function() {}, Mi = function(e) {
        function t(t, n) {
            var r = e.call(this) || this;
            return r.locale = t,
                   r.deprecatedPluralFn = n,
                   r
        }
        return (void 0)(t, e),   <-------------- Error
