cava: shmem input crashes with segfault when connecting to squeezelite

Using the latest source from the github.com master branch, cava crashes on MacOS Monterey when connecting to a local squeezelite instance via shmem. Using cava without shmem / setting it to use portaudio works fine.

Seemingly random, I get input_shmem: source: /squeezelite-ac:bc:32:7a:2d:99cava(20773,0x1080b0600) malloc: Incorrect checksum for freed object 0x7fef8303dc00: probably modified after being freed. Corrupt value: 0x4061a00000000000 cava(20773,0x1080b0600) malloc: *** set a breakpoint in malloc_error_break to debug zsh: abort cava

I hope I can give the correct information to reproduce below. Otherwise please give me hint concerning what I am doing wrong…

To Reproduce Steps to reproduce the behavior: 0. Start squeezelite with vis output

1. Configure cava to use shmem with noncurses
2. run cava
3. wait
4. See error

Expected behavior No error ;o)

Desktop (please complete the following information):

• OS: macOS
• Version 15.1

Terminal emulator

• MacOS Terminal with zsh

Additional context The latest output_vis.c of squeezelite is here (https://github.com/ralph-irving/squeezelite/blob/master/output_vis.c). Maybe that helps.
