panic when trying to run the wss broadcast example

[akiross]

Hello,
today I was trying to use websocat to broadcast messages over wss, but it panics with this message:

thread 'main' panicked at 'lint should have caught the missing pkcs12_der option', src/ssl_peer.rs:228:10

Here a run enabling the backtrace

$ websocat --version
websocat 1.11.0

$ RUST_BACKTRACE=full websocat -t wss-l:127.0.0.1:4445 log:broadcast:mirror:
websocat: Unfortunately, serving multiple clients without --exit-on-eof (-E) or with -U option is prone to socket leak in this websocat version

After the server was started, the client was used like this:

$ websocat wss://127.0.0.1:4445
websocat: WebSocketError: WebSocket SSL error: Connection reset by peer (os error 104)
websocat: error running

This happens both with the nix packaged version and using containers, so I don't think it depends on how it was built:

$ podman run -it --rm --net=host docker.io/vi0oss/websocat:0.11.0 -t wss-l:127.0.0.1:4445 log:broadcast:mirror:
websocat: Unfortunately, serving multiple clients without --exit-on-eof (-E) or with -U option is prone to socket leak in this websocat version
thread 'main' panicked at 'lint should have caught the missing pkcs12_der option', src/ssl_peer.rs:228:10
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

EDIT:
trying with containerized version 0.10.0, it seems it catches the problem:

websocat: SSL listerer and --pkcs12-der option should go together

[vi]

lint should have caught the missing pkcs12_der option

Something happened to the CLI options checker. This error should only be observable with --no-fixups option.
