Comment with "global" at the beginning causes TypeError

[0ptional]

The following file causes a TypeError: Cannot read property 'type' of null Error:

export const VARS = {
    /* global something */
    prop: 'value',
};

It seems like the global with anything after that causes the error. If I write Global it works. If I remove something it works.
Using /** or // works too.
