TypeError: Cannot read property 'type' of undefined in TypeScript 1.8 beta

[bdespres]

Using TypeScript 1.8 beta with the "--allowJs" flag to compile a .js file with JSDoc comments causes a compiler crash for any file JS containing a JSDoc @return comment. For example:

/**
 * @return the number 5
 */
 function five() {
    return 5;
 }

% tsc --allowJs --outDir /tmp test.js

                throw e;
