Hi,

and it does so if .gitignore has not been committed yet. This is with
git version 2.6.3. To reproduce:

mkdir test
cd test
git init

echo "test" > test
echo "something.txt" > .gitignore

git add test .gitignore
git commit -a -m "init"

mkdir node_modules
echo "something" > node_modules/file.txt
echo "node_modules" >> .gitignore

git stash save -u

Now node_modules will be deleted even though it was ignored at the time
of the "git stash save -u". Apparently .gitignore is reverted first,
then the cleanup is done taking the new state of .gitignore into account
where node_modules is now untracked and not ignored anymore, thus
deleting it.

I think this should be considered a bug that can cause data loss, even
if only in rare cases.

thanks,
  Michael
