Typically one would do this:

1) confirm the problem does not exist in the oldest commit and does 
exist in the latest commit: git checkout oldest, test, git checkout 
master, test
2) git bisect start master oldest
3) do a test, then either git bisect good or bad
4) repeat step 3 lots of times

If you are lucky enough to know a specific source commit that either 
does or does not have the problem, you can find the bibisect repo commit 
with this:
