Follow-up Comment #2, bug #15579 (project kawa):
But the problem is not a set-car! on a constant. The
problem is append-map assuming that the value
returned by the function will not be used again. Consider:
(append-map (lambda (x) (hash-table-ref/default ht x '())) ls)
I don't want the values on my hash table to be modified
by append-map, and all those values are created with
cons, not quote.
