Hi Brian,

Strange indeed.  Here's what I would suggest:

1. For debugging output:

 $ echo 'prefix=/usr/local' >>config.mak; # or whatever prefix you use
 $ git describe
 $ gcc --version
 $ wget 'http://download.gmane.org/gmane.comp.version-control.git/128067/128068'
 $ git am -3 128068
 $ make
 $ bin-wrappers/git checkout m

2. To track down the issue, if you like to read assembler:

 $ make builtin/checkout.s
 $ vi checkout.s

Good luck,
Jonathan

Yeah, I would be curious to see the output of that. Interesting, too,
that it seems to happen with multiple commands (it looked like it
happened with "git push foo" in the pastebin from the irc log).

Ugh. I think a better course of action is to find out which option is
being munged (from step 1 above), and then try running it under gdb with
a watch set on that option struct. Assuming it's easily reproducible of
course.
