The only thing this patch does is run the pager, so presumably git-diff _is_ generating output, but calling the pager is broken for some reason. What is the value of $GIT_PAGER and $PAGER on the broken and working machines? Can you confirm that the pager works on both machines?

I couldn't reproduce on my 32-bit or 64-bit machine (the former running Debian unstable, the latter Debian stable). But given the patch you bisected to, I think it is more likely that your pager is broken on the 64-bit machine.
