fish: Job 1, 'tizonia --soundcloud-user-likes' terminated by signal SIGABRT (Abort)

Tizonia cannot play audio on CachyOS.
Tizonia uses tizonia-all-git 0.22.0+28.r3903.20210110.a1e8f8bd-9 from AUR.

@wkr111: Suggestion: Make the issue title more precise, e.g.
"Crashes with `Fatal glibc error: malloc.c:2607 (sysmalloc): assertion failed: (old_top == initial_top (av) && old_size == 0) [...]`".

I get this also:

I tried to compile with debugging options, but that fails with linking errors.

So I can only give a GDB session with backtrace for tizonia compiled without debugging options: gdb --args tizonia https://vimeo.com/587901188:

Hello;

I have rebuilt tizonia in debug mode. And those are the results when I run it. At the end you can see that it crashes if I try to play something
