Thanks, I seem to have misunderstood how the coverage build works.  

What is SANITIZER set to in this case?

Does this pass the coverage test in the oss-fuzz repo?

https://google.github.io/oss-fuzz/advanced-topics/code-coverage/

To test, change the projects/samba/Dockerfile to point at your branch
to test:

https://github.com/google/oss-fuzz/blob/master/projects/samba/Dockerfile#L19

The 'infra/helper.py shell' command can be quite helpful debugging this
stuff.

Thanks!
