New description:

 When compiling a Scheme program containing "many" constants that are
 reasonably large, the resulting binary will segfault.

 {{{
 #!scm
 (use-for-syntax srfi-1)

 (define-syntax generate-literals
   (ir-macro-transformer
     (lambda (i r c)
      `(begin
         ,@(list-tabulate
             1000
             (lambda (x)
               `(define ,(gensym) (quote ,(make-vector 1000)))))))))

 (generate-literals)
 }}}

 This happens with vectors as well as lists (but not strings, because those
 are allocated statically with {{{malloc()}}})
