Details:

Apparently Kawa can't dump circular literals.  Given this file:

(define (foo) '#1=(0 . #1#))

the compiler aborts with an error:

shell> kawa --version
Kawa 1.14.1 (revision 7749:8044M)
shell> kawa -C test.scm 
(compiling test.scm to test)
Exception in thread "main" java.lang.Error: no method to construct ClassType
