One way is, before *each* compilation after a 'git bisect good/bad', to do
a 'git cherry-pick 10fd883ce3847'. This means you don't actually move it
after the commit that causes the problem, but you do add it on top for
your compilation.

But that means that after testing the build you can no longer do a simple
'git bisect good/bad' as that would tag the cherry-picked commit instead of
the one you tested.

So instead you have to do 'git bisect good/bad HEAD^' (assuming you did a
single cherry-pick) [1].
This will automatically "remove" the cherry-picked commit again, which is
why you have to add it back for your next iteration.


[1] Or you can specify the commit ID of the commit you're really testing.
