Actually, and strangely, I get a different error when running under
LLDB.

  Loading /Users/gerd/emacs/savannah/igc/lisp/emacs-lisp/cl-generic.el 
(source)...
  Loading /Users/gerd/emacs/savannah/igc/lisp/simple.el (source)...

  Error: error ("Eager macro-expansion failure: (setting-constant 
byte-compile-form-stack)")
    signal(error ("Eager macro-expansion failure: (setting-constant 
byte-compile-form-stack)"))

In a way that makes more sense because we saw that "Eager..." string
before. byte-compile-form-stack is a var defined in macroexp.

Does someone know what "eager" macro expansion means? In what way is it
eager? Or different from non-eager (lazy?) macro expansion? But why
would ME be lazy? Questions about questions...
