Does anyone recall fixing this one at or near
dfe46c5ce6e68d682f80f9874f0eb107e9fee797? There was a rewrite of sha1_file.c
including link_alt_odb_entry where I am finding memory corruptions. I think
I'm chasing something that was already fixed some time after 2.13.5 but the
common parent to where I am is pretty far back compared to master.

Thanks,
Randall
