Bus Error- git merge

[Brian Moran <bmoran@onehub.com>]

I am getting a bus error on a git merge, including the more recent versions.
Following the instructions from a bug August, I got the latest sources,
compiled them up, and executed the merge in the debugger to repro. Here¹s
what I found:

gdb ../git-1.6.1.2/git-merge

Any suggestions on how to proceed? I am available to gather more information
on this as I can reproduce at will.
Thanks,
