Yes! Thanks for sharing this fix. I applied the same changes to my code and now I don't encounter the bug anymore. I tested the patched code with both guile-2.2 and guile-3.0. Do you know whether this will also work with guile-2.0? (I'd like to keep things compatible with guile-2.0 for a few more years). Kind regards, Roel Janssen
