I think you're just experiencing an oddity with xkbcomp and if
you want to report an issue, it is with the X11 project that you
should be talking, this one has nothing to do with bash.

The problem is that xkbcomp (for whatever reason) wants to
unlink the file it is going to write to before creating a new
one, and, kind of obviously, no matter what magic name you
give, you cannot unlink stdout.

You can however do (or at least, on my system, I can do)

        xkbcomp -o - $DISPLAY

and that seems to work (it is often worth testing whether "-"
works for stdin/stdout when all else has failed - programs
sometimes special case that name).
