Tsc compiler hangs (3.4.0-dev.20190226 and above)

[martis347]

Hello,

I've encountered to some issues after updating typescript to the latest stable version. With versions 3.3.4000, 3.4.0-dev.20190223 it's working, with every later version it just hangs.
It is using styled components, but the issue seems not to be there.

TypeScript Version: 3.4.0-dev.20190226 and above (up until 3.5.0-dev.20190404)

Search Terms: typescript 3.4.0 hangs, typescript 3.4.0 no response, typescript 3.4.0 compiler unresponsive

Code

import baseStyled, { ThemedStyledInterface } from 'styled-components';

interface Theme {
	color: string;
}

const styled = baseStyled as ThemedStyledInterface<Theme>;
console.log(styled);

Expected behavior:
It compiles in <5 seconds

Actual behavior:
Tsc does not compile, just hangs and uses a lot of CPU power.
