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())

OK, looks like this is a size calculation problem in C_rereclaim2 (see chicken-hackers thread).
