Hello

I'm stuck with an Emacs but. I run 21.4 on Lunar Linux.
I can't save my buffer. Emacs complains about "Lisp nesting exceeds
max-lisp-eval-depth". Each time I hit C-x C-s or the Save menu it yawns....


Here's my ldd emacs:

And here's my debug buffer :

It appears that you have (re-)loaded loaddefs.el after vc-cvs.el was
already loaded, which has overwritten the definition of vc-cvs-registered
from vc-cvs with the dummy in loaddefs.  You can break the loop by
explicitly loading vc-cvs again with load-library.
