Note, you can use -p to run the command from the command line, in this case:

  yosys -m ghdl -p "ghdl register_file"

Which produces the same error, then exits without having to type "exit" from the
interactive mode.

Meanwhile, we've been engaging with the upstream developers. They merged the
test case from our bug report:

And jeff submitted this issue yesterday, which got a positive reply:

  https://github.com/tgingold/ghdlsynth-beta/issues/70

So we keep chugging along...
