Hi,

When I define a following function:

        (defun my-member (some-list sexp)
          (cond ((null some-list) nil)
                ((equal (first some-list) sexp) t)
                ((equal (rest some-list) sexp) t)
                (t (or (my-member (first some-list) sexp)
                       (my-member (first some-list) sexp)
        ) )     )  )

the `gcl' interpreter accepts it (it is syntactically correct).
However, when I later invoke it as follows:

        (my-member '(1) 'a)

I see

        Error: Caught fatal error [memory may be damaged]
        Fast links are on: do (si::use-fast-links nil) for debugging
        Error signalled by EQUAL.
        Broken at EQUAL.  Type :H for Help.

when I try the same query again I see

        Segmentation fault

My program contains an error but running it should not cause segfaults,
I guess. Different interpreter (clisp) reports correct run-time error.

Regards.
