Typescript Issues with `crypto-js`

[mrowles]

Describe the bug
The crypto-js library is forcing a typescript@2.9.* compilation error when using angular@6.* AOT compilation flag. The error seems to be with the getJSDocTags function (see errors below).

I have tried installing @types/crypto-js, installing crypto-js locally, setting the allowJs flag in the tsconfig.ts file..no combination seems to work.

Upgrading to angular@7 and typescript@3 does not fix this issue.

There is more discussion going on at the TypeScript register, but thought it should be raised here additionally:

• Module build failed: Error: Debug Failure. False expression. microsoft/TypeScript#25067 (comment)
• Crash in getJSDocTags on const a = b = () => 0; microsoft/TypeScript#24963 (comment)

To Reproduce

Steps to reproduce the behavior:

1. Setup new angular@6, webpack@4 + typescript@2 project
2. Install aws-amplify + add some auth flow
3. Compile using webpack with AOT flag

Expected behavior
I expect the compilation to be successful and production ready JS files are created.
