source-map-support bug

Steps to reproduce:

• Run npm install
• Execute the npm run babel

Acutal output:

Note that only the first function name is correct. They seem to be off by one. The line numbers and columns are correct though.

Error:
    at foo (/my-project/src/foo.js:5:15)
    at foo (/my-project/src/foo.js:9:3)
    ...more

Expected output:

Error:
    at foo (/my-project/src/foo.js:5:15)
    at bar (/my-project/src/foo.js:9:3)
    ...more

You can also run npm run terser, this issue is also reproducible with terser.
