If you are using Git for Windows, I believe that there is a known issue [1] which was patched in the MSYS2 runtime used by GfW [2].

It does not appear to be released as part of a tagged version of Git for Windows yet, although from reading [1] it appears to be planned soon. In the meantime, you should be able to work around the issue by using a snapshot of Git for Windows.
