This is bad.

index-pack works like this:

1) it receives data over the network:
   1a) it writes a copy of that data to disk to create a pack
   1b) it deflates that data in parallel to compute its SHA1

2) when done, it resolves deltas and to do so:
   2a) it deflates the base object data from 1a
   2b) it applies the delta over the base object data then compute its 
       SHA1

In your case it seems that 1B and 2A don't produce the same deflated data somehow.

Is it reproducible? Are you using Linux? What kernel version? Are you using NFS?

If it isn't reproducible then you might possibly have been the victim of faulty hardware.
