• If the problem was occurring with a specific repository, can you provide the
  URL to that repository to help us with testing?

No problem with git itself.

• Further Info:

Problem started to rise when git updated itself to 2.19.2 version (or may be an earlier version, as I installed git multiple time to may resolve the issue, but I'm sure the version is no more than 3 weeks old.).
I tested the portable version on a new installation of windows 7 32-bit and on a Windows 10 64-bit, on all of them git-bash.exe execution crashes by segmentation fault.
I tried to remove all configs and setting in E:\Users\[UserName]\, but problem didn't resolved.
I tried to run the git-bash.exe as administrator, but problem didn't resolved.
On same machine cygwin installation works.
On same machine /bin/bash starts without problem.
On same machine git-gui.exe and gitk.exe start without problem.
On same machine /usr/bin/mintty.exe starts without problem.
On same machine git-cmd.exe starts without problem.
On the windows 10 machine, git-bash.exe from git verison 2.14.2 works.

This has been reported before, and is one of the two reasons why v2.19.2 was demoted to "pre-release" status.

Normally, I would have published a v2.19.2(2) in one big hurry, but there have been more changes in the pipeline which would be very hard to roll back just for a v2.19.2(2), and I am rather busy with preparing the Windows side for v2.20.0 (which is now expected Dec 10th).

So please, for the moment, either switch to a snapshot (https://wingit.blob.core.windows.net/files/index.html) or downgrade to v2.19.1, until v2.20.0 comes out.
