Invalid source maps generated

[wagenet]

We're seeing situations where we get source maps with negative line numbers. I believe it only occurs in some of our TypeScript files. I hope to add more details to this ticket, but wanted to get something started for reference.

See also emberjs/ember-cli-babel#364

Thank you!

[wagenet]

Our primary version of ember-cli-typescript is 4.0.0 and ember-cli-babel is 7.22.1.

Turns out that we are seeing this in some non-TS files as well. I'm not certain if that rules out ember-cli-typescript or not.

@wagenet did you all ever get further info on this? Based on this writeup and your comments in Discord at the time, my understanding is that this is not ember-cli-typescript related, but would like to confirm before I close this.

@chriskrycho I believe it is probably related to what is being discussed at emberjs/ember-cli-babel#364. I'll close this one.

Thanks for clarifying! I'll go watch that issue with much interest.
