assert failed in pathspec.c

assert failed in pathspec.c

[Dingyuan Wang]

Hi all,

I've got an assertion error when `git add .`

git: pathspec.c:317: prefix_pathspec: Assertion `item->nowildcard_len <=
item->len && item->prefix <= item->len' failed.
Aborted (core dumped)

I think the repo doesn't have anything interesting.
No submodules or subrepos. It's like:

repo/
 .gitignore
 .git/
 scripts/
  .gitignore
  foo.py
  bar.json
 something/
 someanother/
 other/         (gitignored)
  scripts.git/  (original .git for scripts/)
  foo.txt

With

modified:   ../something/a.txt
modified:   ../someanother/b.txt
...

Working directory is repo/scripts.

I think the bug is related to this post: [assert failed in submodule
edge case](https://marc.info/?l=git&m=142894416621088&w=2).

Thanks for the bug report.

What does
git --version
give you ?

And what happens, if you run the latest version of Git ?

Re: assert failed in pathspec.c

[Dingyuan Wang]

git version 2.7.0.GIT (latest git master)

Sorry, I have found out that this problem is exactly the same as the
previous post I mentioned.

When I created the repo, scripts/ was a subrepo, and then I moved
scripts/.git out. If I add files in the scripts/ dir, SIGABRT.
