"Segmentation fault" error when trying to run

It seems I'm cursed regarding this thing...

Segmentation fault

I have libfluidsynth2 2.1.7 installed; I don't have pulseaudio installed but apulse instead.
Inxi info about GPU:

EDIT:
Installed PulseAudio; now instead of this part:

fluidsynth: error: Failed to create PulseAudio connection
WARNING: I_InitSequencer: failed to create audio driver

I get this one:

fluidsynth: Using PulseAudio driver
WARNING: CVar s_soundfont doesn't point to a file.

What's wrong with this setup?
Thanks yet again beforehand.

Hmmm this segfault could be the vsync setting, I tested it on my Linux box (HD620) and it was ok. What you can try is, in gl_main.c there will be a call to SDL_GL_SetSwapInterval. Comment out this function call and see if that works for you.

Sorry, no dice; exact same errors...

Finally solved on #29 . Let's look forward a "stable" milestone of the project in the future. Thanks.
