this looks odd… Git bisect is used to find the commit that introduces a regression. Maybe it's worth having a look at a tutorial of your choice, the workflow should be sth. like: git checkout next git bisect reset git bisect start git bisect bad git bisect good v0.9.1 compile / run / test if fail -> git bisect bad; else git bisect good and repeat the last step until you spot the commit.
