CRT error when running git-2.9.3.2

I`m testing git-2.9.3.2 at r72486

https://github.com/git-for-windows/git/releases/download/v2.9.3.windows.2/Git-2.9.3.2-32-bit.exe

Installation worked fine. However, when running "git init" under the git bash shell
(mingw32) the following error message appears
"error: Tweaking file descriptors doesn`t work with this MSVCRT.dll"

(This does not happen under Windows XP)

I`m submitting an screenshot and a debug log. My guess is that the problem is related to the line
fixme:(sdk/lib/crt/stdio/file.c:1712) : pmode 0x01b6 ignored

in the debug log.

Some other problems:
1) two windows of "minitty.exe" are kept open. This does not happen under Windows!
2) The shutdown was not clean (but this is probably unrelated)
