Panic: `source slice length (16) does not match destination slice length (20)`

[aykevl]

Describe the bug After running for a while, librespot crashes with a huge stacktrace.

To reproduce I don't know, I think I just left it running for a few hours. Note that my internet connection is weird (see https://github.com/Spotifyd/spotifyd/issues/1211) so that might have something to do with it. I am hopeful though that the stack trace provides enough clues as to why it crashes.

I'll provide additional information if it happens again.

Log No full log, but here is the stack trace:

Host (what you are running librespot on):

• OS: Linux (ARM64)
• Platform: Raspberry Pi 3 Model B Rev 1.2

Additional context Weirdly, librespot just continued running after what looks like a fatal error to me. From the log it appears that I was trying to start playing some music (which didn't last long due to https://github.com/Spotifyd/spotifyd/issues/1211).

Please provide version information.

Sorry I forgot, this was the dev branch at the time I made the issue.

[roderickvd]

It sometimes happens that the packet isn’t received fully. I thought I had made that piece of the code panic-free but I guess I missed something.

Got a new stack trace:

As the stack trace says, this is librespot f037e46. I will try to get a stacktrace with debugging information next.

[roderickvd]

Other than that it would be nice to make it panic-free, I see at the beginning of the log that it fails to bind, that the address is already in use?

I'm not sure why that is. Maybe I was running another librespot instance at the same time, or maybe it's because I have a WireGuard network interface too that librespot doesn't seem to like very much.

(I have now switched to libespot-java because that's the only thing that will work correctly on my network, feel free to close this if there is nothing important to fix).

ye it works with Java not Rust for some reason
