Can you just email the compressed one to me as an attachement, I'll put it somewhere..

Yes and no. There obviously are several "close(3)"s in even that short snippet, but they are for a different kind of close - they are for the regular loose object open/mmap/close/munmap sequence which has re-used that file descriptor.

So the *incorrect* close(3) happened some time much earlier.

The other alternative is, of course, that the 3 itself is just wrong, and something corrupted the packfile data structures.

It would obviously be interesting to see the base repository and the commit you are trying to do - is that possibly publicly available?
