[Gcl-devel] Re: [Axiom-developer] Broken hypertex

Greetings, and thanks for the report!  Typeo should be gone now in
both branches.

Just wanted to note that the only way you can guarantee that you don't
get a copy out of object_to_string is to write a null character at the
end of the lisp string body yourself, as there is extra room only in
special circumstances.

Take care,
