Dear all,
Thank you for the quick replies. My bug report seems indeed about the
same issues as in bugs #18156 and #42334 reported by Michael Welsh
Duggan and Kévin Le Gouguec earlier.

Thank you. I will look into these, and I believe they can help me solve
problem 2) in my original email.

This seems to be it! I have not given a try to the patch yet, but I am
quite certain this is the same issue. Kévin's description (bug #42334)
matches my issue very well. Since this part of the code is very old, I
do understand that you would hesitate changing it, in which case this
can be closed from my part. I guess I didn't find these because I was
looking only at unarchived issues in debbugs.gnu.org.
Best regards,
Emilia
