Hmm. It would help to know what object it is failing on. I assume you
repo is too large to be easily shared? If not, can you try instrumenting
hash-object with the patch below and seeing which file it is barfing on?

I'd be curious to see the size of the file (in case it is >2G and we
have another signed integer problem) and its position in the list (in
case we are leaking memory and you are hitting a system limit).
