Wow, that's remarkably old, for software anyway.
It may well have been created by Bill Schelter himself.

In case it matters, that should probably be all_dotsimp_denoms.
(Maxima was changed to case sensitive, with lower case preferred,
some years ago).

My first guess is that SBCL (new version) is catching this error
while GCL (old version) is letting it pass. When I try the examples
you gave with Maxima 5.20.1 + GCL on Windows, I get some
plausible outputs; I don't know enough about affine to say if they
are correct, but anyway there is no error detected.
Can do try this:
:lisp (setq *debugger-hook* nil)
and re-run the examples. When you get an error,
it will give you a Lisp prompt where you can get a stack trace.
Something like :backtrace or :bt prints the stack trace, sorry,
I don't remember for sure. Please post the stack trace, then
we'll be able to see where the error is. Not sure if we'll be able
to fix it but it's worth a try.
Sorry I can't be more helpful,
