Comment (by sjamaan):

 {{{
 #!scm
 (define (constantly x) (lambda () x))
 (print (equal? (constantly (string)) (constantly (string))))
 }}}

 If you compile this with {{{-no-lambda-info}}}, it prints {{{#t}}}.  If
 you compile it without this option, it'll print {{{#f}}}.  This is due an
 off-by-one where comparison would skip the final slot in the closure
 object and needlessly compare the headers. Patch sent to chicken-hackers.
