Anyway, before posting the result of any commit as the buggy commit from a git bisect, it is best to confirm it by: 1) Checking out the tree at the bad commit. 2) Verify that the tree at that point is bad 3) Check out the parent of that commit (the commit before the bad commit was applied). 4) Verify that the tree at that point is good May need to repeat the above a couple of times, in case the issue is not 100% reproducible. If the above is true, then post the patch as the bad commit. If it is not, then something went wrong with the bisect. -- Steve
