--- Comment #2 from Eli Zaretskii <eliz at gnu dot org> ---
The culprit is this commit:

  commit d08cbc5d3203118da5583296e49273cf82378042
  Author:     Andrew Burgess <aburgess@redhat.com>
  AuthorDate: Wed Dec 22 12:57:44 2021 +0000

      gdb: unbuffer all input streams when not using readline

I guess the detailed analysis in that commit, which describes the behavior =
of
glibc and the Linux kernel, doesn't fully apply to MS-Windows and its C
runtime...

The patch I proposed, which partially reverts that commit, fixes the issue =
for
me on MS-Windows.  But if we want to keep the current code for GNU/Linux and
other platforms, I guess the actual fix will need to be more complex.
