This project contains source files that seem to cause the TypeScript compiler (v3.3.3) to crash.

To reproduce, clone this repo, then run the following:

npm i
./node_modules/.bin/tsc --pretty --target es5 --outDir lib-commonjs --module commonjs --project "./tsconfig.json"

Expected behavior

This is a trimmed down repro of an issue encountered in a larger project. It is not expected to compile sucessfully, but should print several error messages.

Observed behavior

tsc runs for several minutes comsuming 100%. Eventually the node process exits with this error:
