While I do get this warning message using the Maxima substitute from hydra.gnu.org, when I build Maxima 5.41.0 from source locally, this warning message does not appear. Is this the case for you as well? The message comes from the source code of GNU Common Lisp, but the GCL binary from hydra.gnu.org doesn't give this error when I run it. It seems like this comes down a bug in GCL set off by Maxima, a bug in Maxima, a reproducibility issue, or some combination of all of these. I'll be investigating this further.
