I get the following output:

    rsv/arbitrary-null.scm:81:20: In procedure read-null-value:
    Wrong number of arguments to Segmentation fault

When running the commands:

    git clone https://codeberg.org/kakafarm/guile-rsv/ # Clone my repositor=
y.
    cd guile-rsv
    git checkout segmentation-fault # Should be commit number
790ee10036f3dcb425fbf5619ff0e452a73d459d
    printf "\xfe" | ./rsv2scm # This is the offending command.

I accidentally called the procedure read-null-value without any
arguments, while the procedure needs three arguments.  Instead of
showing a useful error, it results with in a segmentation fault.

My guile --version:

    guile (GNU Guile) 3.0.9

It came from a Guix installed on a Debian installation.  The Guix
repository commit obtained from the guix describe command is
3de361d9c9d320aefbd43710124d7b07af891de1.

Thank you,
Yuval Langer.

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=
>.
    This is free software: you are free to change and redistribute it.
    There is NO WARRANTY, to the extent permitted by law.

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? _ # _)
    In unknown file:
               6 (apply-smob/0 #<thunk 7fcdb7dbc300>)
    In ice-9/boot-9.scm:
        724:2  5 (call-with-prompt _ _ #<procedure default-prompt-handle=E2=
=80=A6>)
    In ice-9/eval.scm:
        619:8  4 (_ #(#(#<directory (guile-user) 7fcdb7dbfc80>)))
    In rsv2scm:
        13:12  3 (main _)
    In rsv/arbitrary-null.scm:
       144:23  2 (rsv->scm #f #<input: file 0>)
       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.
