Segmentation fault for git commit command (Windows)

Running git 2.15.1.windows.2 on Windows 10 x64 v1709

For me the problem was caused by a faulty index. To resolve I ran the following from the project directory:

rm .git/index

git reset

As you can see from the image in this link, I didn't loose any changes by performing a reset.

If you already have Git installed, you can get the latest development version via Git itself:

git clone https://github.com/git/git

but this didn't work for me.I uninstalled the git and then again downloaded then my problem got resolved.

I have resolved the problem. The last git version (2.13.1) has the bug - it has been released 05.06.2017. I installed previous version (2.12.2) and now all is OK.
