1852	csc is absurdly inefficient when compiling large procedure calls	zaifir		"Try compiling the following trivial module with CHICKEN 5:

{{{
(module foo *
  (import (scheme))
  (define bar
    (list (make-string 0)
          (make-string 1)
          ;; ...
          (make-string 4999)))
  )
}}}

That's an invocation of `list` to 5000 `make-string` invocations. On my system, this generates a > 15 MB C source file, which takes at least 10 minutes to compile (I gave up & sent a SIGTERM).

Replacing the list with a 5000-element vector & then converting to a list, e.g.

{{{
  (define bar
    (let ((vec (make-vector 5000)))
      (vector-set! vec 0 (make-string 0))
      ;; ...
      (vector-set! vec 4999 (make-string 4999))
      (vector->list vec)))
}}}

results in fairly normal compilation times. But this is a very ugly workaround when your intention is to compile a procedure call with a large number of arguments.
