Segfault on git for Windows

Segfault on git for Windows

[Rémi Galan Alfonso]

Hello,

I am unsure whether it's Windows only or not, so I'm sending here and
CCing Dscho.

At $DAYWORK, the code is versionned under SVN. Since I haven't used
SVN before and try to have a clean and bisectable history, I installed
git with the intent to manage my code locally before pushing to SVN
when I'm satisfied (I haven't tries git-svn because I have never used
it and would like to avoid screwing up the SVN repo by some mistake).

So first to setup the local repo, I wanted to add all of the code
files. So I first ran at the root of the repo:
  $ git add ./**.cpp
Which is quite a big amount of files (partly because of external
dependencies which would have been smart to exclude, but it's
done).
  $ find -type f -name "**.cpp" | wc -l
  8676
This command worked (return status is 0 and no error message).

However following `git add **.hpp` and `git status` segfault with no
additional message:
  $ git status
  Segmentation fault
I didn't try to test other commands (`git diff --cached` works
though).

$ git --version
git version 2.12.2.windows.1

This seems to be reproducible.

Sadly I won't be able to share the repo where this happens.

FWIW:
  $ git fsck
  notice: HEAD points to an unborn branch (master)
  Checking object directories: 100% (256/256), done.
  notice: No default references

Thanks,
Rémi Galan Alfonso

I think this is the problem identified in
https://github.com/git-for-windows/git/issues/1111.

To verify, you could try the snapshot (with the proposed fix) hosted here:

Ciao,

Thanks, it fixed it. Sorry for the noise.
