Can you apply this patch, rebuild git and retry again? It will create a coredump at "fatal:...", which might give me a clue what's going on.. Once you get the coredump, open it with gdb, execute "bt full" and paste the output here.

diff --git a/usage.c b/usage.c
index ed14645..0403091 100644

+       *(char*)0 = 1;
        exit(128);
 }
