[Larceny-users] Bug in bytevector-s32-set!

[Ray Racine]

;; first set bytevector to -1 then read it back, did not get expected -1

(let* ((bv (make-bytevector 4 0))
(show (lambda () (display bv)(newline))))
(newline)
(show)
(bytevector-s32-set! bv 0 -1 'little)
(show)
(bytevector-s32-ref bv 0 'little))


#vu8(0 0 0 0)
#vu8(255 255 255 127)
2147483647

;; ref a little endian int from #vu8(255 255 255 255) and get -1,
;; expected behavior

(let* ((bv (make-bytevector 4 255))
(show (lambda () (display bv)(newline))))
(newline)
(show)
(bytevector-s32-ref bv 0 'little))

#vu8(255 255 255 255)
-1

Ran across the above while writing a quick utility using Larceny's FFI
to IBM's MQ (mq-mgr on OS/390 mainframe) today. ?!?!?

This weekend I'll try and get around to sending out some quick patches
on some of these little bugs I've managed to stumble across.
