I omitted it because it didn't seem to matter -- the segfault does
not occur if I simply change print to display in the main loop. Well,
that once in the main loop, since it's also called from the default
value of escape.
However, here it is:
(define (%string-charset->pred obj)
(cond ((procedure? obj) obj)
((list? obj) (lambda (c) (memq c obj)))
((string? obj) (%string-charset->pred (string->list obj)))
((char? obj) (lambda (c) (char=? c obj)))))
It simply creates a predicate from "abc" or '(#\a #\b #\c) in the
same way.

I am not, and should have said so. The code that crashes is
interpreted, not compiled, and gsi was built with just the standard
options. I didn't even bother with --single-host or anything when I
installed it.

Ah. That's surprising. I'll go ahead and try to duplicate the fault
then, and see if I can get get gdb to help me narrow in on the
problem. Thanks, and other thoughts are welcome.
