git@blackwidow ~/metux/work.git/pack $ git index-pack pack-3b6cbd5dc5f54cf390cfaa479cac6a99d7401375.pack
error: inflate: data stream error (incorrect data check)
fatal: pack has bad object at offset 37075832: inflate returned -3

(that's essentially the same git-gc says)


git@blackwidow ~/metux/work.git/pack $ git unpack-objects -r < pack-3b6cbd5dc5f54cf390cfaa479cac6a99d7401375.pack 
error: inflate: data stream error (incorrect data check)
error: inflate returned -3

error: inflate: data stream error (incorrect data check)
error: inflate returned -3

Unpacking objects: 100% (1223/1223), done.
fatal: final sha1 did not match
