Hi Mark,

having a look here, the trouble is that the compiler is presented with a
function named "teco:type-1-\^M".  The ^M is the trigger for the bug
while converting the lisp function name in a valid symbol name for the C
toolchain.  The fix should cover all characters below 15 that might
appear in a symbol.

I've installed a fix on master as e7699bf290, please have a look if it
works for you as well.

Maintainers will tell us if we want to backport it on emacs-28 as well
(I think would be worth).

Thanks

  Andrea
