srfi-41 segfaults on non-stream cdr

[Jim Ursetto]

Quickest way I can reproduce this:

(use srfi-41)
(stream-null? (stream-cdr (stream-cons 1 2))
Process scheme segmentation fault

(stream-cons 1 2) is illegal but should not segfault when dereferenced.

Fixed in 1.2.2.

#;2> (stream-null? (stream-cdr (stream-cons 1 2)))

Error: bad argument type - not a stream: 2

Report will potentially be very "far" from point of actual error. Since lazy execution of tail will not discover type mismatch until forced.
