  • Any other interesting things about your environment that might be related
    to the issue you're seeing?

Not that I can think of.

Details

  • Which terminal/shell are you running Git from? e.g Bash/CMD/PowerShell/other

Git Bash.

git init foo
cd foo
echo foo >foo
git add foo
git commit -m 'Add foo'
echo bar >bar
git add -N bar
git stash
  • What did you expect to occur after running these commands?

I expected Git to stash the changes to bar.

  • What actually happened instead?

Git produced the following output:

error: Entry 'bar' not uptodate. Cannot merge.
Segmentation fault

It also left behind .git/lock, so running git stash again produces the following output:

fatal: Unable to create 'C:/TEMP/foo/.git/index.lock': File exists.

Another git process seems to be running in this repository, e.g.
an editor opened by 'git commit'. Please make sure all processes
are terminated then try again. If it still fails, a git process
may have crashed in this repository earlier:
remove the file manually to continue.
  • If the problem was occurring with a specific repository, can you provide the
    URL to that repository to help us with testing?

It doesn't occur with a specific repository.
