Re: Mac OSX, git and mounted drives from linux

Hi,

I think I've found a bug with git. For me it reproduces 100% of the time. Basically "git diff-index HEAD" seems to be broken in some strange way in my situation.

Prerequisites:
- Running git from a mac, latest update of snow leopard
- mounted a volume that exists on a linux box
- perform "git diff-index HEAD" on a repository

Notice also that the output from diff-index changes once in a while when running other git commands. I couldn't find any reasonable pattern. If I run diff-index from the linux box itself just after running it on the mac it outputs the same garbage. If I then pull and then rerun diff-index everything is fine until I run diff-index from the mac again. The reason always running the tools from the linux box is not a reasonable workaround is that GitX uses diff-index :P I have the exact same git version on both machines. I also checked that they are correctly time synched. The full log of what I did to reproduce it (my prompts are prefixed with ------ for readability):
