      Jordan says:

      It’s complicated because it still doesn’t work out of the box, you need my branch which isn’t merged:

      • https://github.com/jordanlewis/debug/tree/fix-bugs… (my branch)
      • https://github.com/golang/debug/tree/master/cmd/viewcore… (the upstream)
      • https://go-review.googlesource.com/c/debug/+/321736… (the CL that isn’t merged yet)

        • Something missing or broken? PRs welcome!
