I.e. git bisect start git bisect bad a1c288f87de7aff94e87724127eabb6cdb38b120 git bisect good e1a6d5cf10dd93fc27d8c85cd7b3e41f08a816e6 and go from there. Hopefully it isn't the merge commit that's being blamed, as that will be far more painful to figure out. --=20 You may reply to this email to add a comment.
