Only first line working?

Why Is only the first line of the stack trace correct? at Generator.next (<anonymous>) and lines with lib/ should not be there.

The same is happening to me on node 10. I'm using typescript to generate the sourcemap. Only the first line is correct. If you need more info let me know.

It's not the only line.

at main (/Users/olalonde/code/binded/filepunk/src/throw-err.js:3:7)
at Object.<anonymous> (/Users/olalonde/code/binded/filepunk/src/throw-err.js:7:1)

The other lines are not in your sourcemap, so what is it you're expecting? (and how is source-map-support supposed to know how to do the thing)

at Generator.next (<anonymous>) [should not be there]

Why? Its in the provided stack trace, do you expect source-map-support to remove the line?
