I see it. Here is a bash script that creates a repository that reproduces the error. It is important that refs which sort alphabetically earlier also point to earlier commits.

-- snip --
#!/bin/bash
git init
echo initial > file && git add file && git commit -m initial
for ((i = 0; i < 1000; i++))
do
	echo $i > file &&
	git commit -m $i file > /dev/null &&
	printf -v l "branch-%04d" $i &&
	git update-ref refs/heads/$l HEAD
done
git gc
-- snip --

On Windows, 'gitk --all' starts with branch-0797, on Linux it starts with branch-0999 aka master.

I'm just throwing this out to interested parties; I'll not look into it at this time.
