Fw: [git-users] git fsck error - duplicate file entries - different then existing stackoverflow scenarios

A user recently asked an interesting question on the git-users list. I think it warrants attentions of a specialists more hard-core than we're there over at git-users.

So I'd like to solicit help if those knowledgeable, if possible.

Subject: [git-users] git fsck error - duplicate file entries -
different then existing stackoverflow scenarios

Hi all,

I have a repo that is giving a 'git fsck --full' error that seems to be different from the existing questions and answers on stackoverflow on this topic. For example, in our fsck error it is not obvious which file is actually duplicated and how/where. And there is no commit sha involved - apparently only blob and tree sha's. But then finding good documentation on this is challenging.

Might anyone have a pointer as to what to read to help figure out a solution/fix to the below? Or know of a solution outright?

Thanks much in advance!
