Comment (by sjamaan):

 This is a bug in `##sys#check-exact`. It will fail anywhere it's used.  In
 core there's currently two places remaining that use it: pointer-vector-
 ref and pointer-vector-set!

 {{{
 (import (chicken memory))
 (pointer-vector-ref (make-pointer-vector 2) #\space) ; segfault
 }}}

 Actually, I think all these uses are bogus: an exact complex number is not
 a valid index into a vector or string. So probably it's better to get rid
 of `##sys#check-exact` altogether.
