GDB TUI broken

[GitMensch]

I have no clue since when this occurs or if this was never working, I guess so, because it is already referenced in #1744...

gdb ./myconsole.exe -x start --> works fine
gdb ./myconsole.exe -tui -ex start --> results in "During startup program exited with code 0xc0000142."

As also analyzed in the referenced issue by @dimztimz this is related to the console handles. The only thing that looks bad is the following, seeing this issue persists over 5 years later:

a new feature that is buggy in a very specific case and that will be sorted out in the future

Maybe the future is now :-)

The work around, as mentioned by him still works:

 gdb ./myconsole.exe -tui -ex 'set new-console on' -ex start

If we can't get that to work reliably I suggest we add a patch to always enable new-console when in tui-mode.

Note: if we do it the other way around it does work:

 gdb ./myconsole.exe -ex start -ex 'tui enable'

(in this case you "obviously" need to temporarily disable the tui to see the display because that doesn't happen on the same console)

If ncurses is updated to the latest patch, then this bug should be fixed (the CreateConsoleScreenBuffer() call was the problem).
