Description
TypeScript Version: 2.5.2
Code
I haven't been able to isolate the exact problem yet, but I have a repo that triggers the bug here: https://github.com/PolymerLabs/polymer-lit
A clone / npm i / npm run build, should show the crash.
The repo uses JavaScript modules, and so imports dependencies by path. I've had to turn on allowJs because otherwise the compiler complains that I'm importing JS (even though this is from a dependency in node_modules, and shouldn't be compiled). But with allowJs enabled, the compiler crashes, presumably somewhere in the Polymer source code.
Expected behavior:
Compiler doesn't crash.
Actual behavior:
/Users/justinfagnani/Projects/Polymer/polymer3/poly-lit/node_modules/typescript/lib/tsc.js:56136
throw e;
