Hi,

I found

(use-modules (rnrs io ports))

(define v (call-with-input-file "EIVE01.DAT" (lambda (port)
  (get-bytevector-n port (* 5 1024 1024 1024)))))

fails due to 'out of range':

ERROR: In procedure get-bytevector-n:

ERROR: Value out of range 0 to 4294967295: 52434042880

 The "count" variable was of "unsigned" type (i.e. 32-bit) so I changed it
to "size_t" and the problem is solved.

Enclosed is the corresponding patch (using format-patch)
