Are you able to share a core file? If not, it would be very helpful for you to 'git fast-export --anonymize ...' and see if you can reproduce the problem on an anonymized copy of your repository. I can speculate about the cause of the crash from your strace above, but a core file would be more helpful. > Is this and edge case for the new algorithm? > > Cheers, > Son Luong. Thanks, Taylor
