Hmm, from this, and a later one ...

... I am reading that (1) the packfile and repository is basically
OK, (2) reading that object sometimes fails, and (3) the symptom is
not limited to fsck but anything that reads the object with
parse_object().  And that symptom exists only on that single machine
(I am assuming that the repository was bit-for-bit copied, not
"cloned", for the purpose of testing it on the other machine).  That
makes me suspect something outside the control of Git (e.g. faulty
memory or disk controller cable).

Are there other big blobs in the repository, and would "show | wc" fail
if you attempt to read it on that machine?

Thanks all for helping to track this, by the way.
