Build git with debugging symbols enabled and run git merge from 1.6.0 under gdb. If it gets a bus error we'll at least get a stack trace in gdb and can see where we were when the corruption killed us. Its a start.
If `gdb git merge` doesn't come up with the corruption then it is the git-merge-recursive backend. Try running it from the libexec directory (see git --exec-path) under gdb and passing into it as arguments:
$(git merge-base HEAD $branch) -- HEAD $branch
where $branch is what you were giving to git merge in the first place.
Again, let us know what the trace is so we can at least narrow down where the corruption killed it. Once we know more than just "it dies" we'll probably be able to ask more interesting questions to help narrow it down.
