Follow-up Comment #3, bug #61748 (project groff):
Hi, Bjarni!
[comment #1 comment #1:]
> I do not get any trouble processing the minimal example.
Thanks for trying. I hesitate to call the behavior
non-deterministic, because it was reproducible with 100%
reliability on my system, but there are obviously many factors
affecting the memory layout of an executable.

Yes, I noticed these too. They are clearly evidence of a bug,
but as it is (as far as I can tell) unrelated to the problem I
encountered, I did not mention it.

Thank you! I had not tried to track that down yet.
