Hi Rudi,
Thanks for taking the time to look at this.

Since you're not seeing the error, here's a variation where I hope you
will:
Attached are the same files with a slight modification.
Functions.lisp has another (defun) and and an explicit (export) form.
To repro:
1) Do a (require).
2) Now comment out the (format) form in the package.lisp file and save.
3) Evaluate (require). Boom!
I received a note from Christophe mentioning that the result when
changing a (defpackage) form inbetween evaluating successive (require)
forms, is undefined.
However, I'm *not* modifying the (defpackage) form itself, merely stuff
inside the package. It seems like a subtle, but definite distinction.
(Note: I found this behavior in the project I'm currently working on,
and the attached example is not an exact replica of my code, but shows
the same end-result.)

Here is the output when I evaluate (require :pak) after making the
changes to functions.lisp and package.lisp.
I get the content of the condition.txt file, and if I choose the "abort"
restart, see this:
CL-USER> (require :pak)

If I choose the "accept" restart, then there's no indication of an error
condition.
Hope this helps.
