bug#68362: Wrong Guile version and a new error message

[Yuval Langer <yuval.langer@gmail.com>]

Sorry,

I have provided the wrong version number used to produce the
segmentation fault.  The true version is:

    guile (GNU Guile) 3.0.5
    Packaged by Debian (3.0.5-deb+3.0.5-4)
    Copyright (C) 2021 Free Software Foundation, Inc.

    License LGPLv3+: GNU LGPL 3 or later <http://gnu.org/licenses/lgpl.html>.

as that is the one specified in ./rsv2scm's shebang.

Using the Guix version:

    $ printf "\xfe" | guile -L . -e main -s rsv2scm

I get the following error:

    Backtrace:
    In ice-9/boot-9.scm:
      1752:10  7 (with-exception-handler _ _ #:unwind? _ # _)

       116:11  1 (row->scm #f 0 #<input: file 0>)
         84:4  0 (read-null-value _ _ _)

    rsv/arbitrary-null.scm:84:4: In procedure read-null-value:
    Wrong number of arguments to 254

The byte value being piped into guile is 254.  Weird.

Thank you,
Yuval Langer.
