Could you give a bit more info on this?
Steps to reproduce?
What OS are you running?

[PJB3005]

The problem seems to be in bzip2 or something, which we don't even have as a direct dependency. Can you run something like lddtree on /home/nuxs/ss13/bin/loader/libswnfd.so?

[PJB3005]

I am also seconding that I am gonna need information on your Linux distro/version at the very least.

[PJB3005]

For some reason (and god this has been a rabbit hole to debug), initializing ALSA (which FluidSynth does when the SS14 instrument menu opens) causes bzip2 to unload from the process.... I'm investigating further and as part of giving up am basically gonna send what I've found to the arch mailing list hoping somebody there is smart enough to figure this crap out.

I cannot believe I am saying this but it appears to be a bug in glibc 2.35 (which released at the start of February). The changelog mention a new dependency resolver algorithm, and if you disable it via GLIBC_TUNABLES=glibc.rtld.dynamic_sort=1, the bug goes away. I also made a tiny test program that replicates this:

#include <dlfcn.h>
#include <stdio.h>
#include <unistd.h>

void main()
{
    printf("honk!\n");
    void* lib;

    lib = dlopen("libfreetype.so.6", RTLD_NOW);
    printf("freetype: %llX\n", lib);

    lib = dlopen("libfluidsynth.so.3", RTLD_NOW);
    printf("fluidsynth: %llX\n", lib);

    // Using dlsym so we don't link directly against fluidsynth and it's dynamically loaded.
    // Function signature matches pretty much.
    void* (*new_fluid_settings_fp)() = dlsym(lib, "new_fluid_settings");

    // Yes, fluidsynth initializes all audio drivers by just CREATING the settings. 
    // Meaning we literally can't stop it from initializing ALSA/PortAudio as a quick workaround.
    void* settings = new_fluid_settings_fp();

    printf("Initialized fluidsynth!\n");

    // GTK3 will fail to load if loaded after fluidsynth initialized.
    lib = dlopen("libgtk-3.so", RTLD_NOW);
    printf("GTK3: %llX\n", lib);

    return;
}

Vera also confirmed this tunable fixes the problem she was having where her client was unable to start consistently.

https://bugs.archlinux.org/task/73967 bug filed with arch linux, I'll file it with glibc as soon as they inevitably tell me it's an upstream issue.

Another user report on the steam forums this time: https://steamcommunity.com/app/1482520/discussions/0/5561388294329160548/?tscn=1647015094

[PJB3005]

Latest version of the launcher specifies the glibc tunable now, so this should no longer happen.
