FMOD_System_Init Crash

Question

I'm trying to use the FMOD audio API in my game but the app starts and then closes. I tried to debug it and the program crashes at the FMOD_System_Init function.

void AudioSystem::Init() {
    FMOD_System_Create(&sys); // FMOD_SYSTEM* sys;
    FMOD_System_Init(sys, 32, FMOD_INIT_NORMAL, 0); // Crash
}

Called here:

int Game::MainLoop(int fpscap) {
    // ...
    // Expose classes to the scripting engine
    // FPS calculations

    m_audiosys->Init(); // AudioSystem* m_audiosys;

    // Initialize Input, Window, Main Game, etc...
    // Game Loop...

    // ...
}

This is the fmod.log file:

It works if I run step-by-step. It goes on a bunch of machine code and if I keep jumping the program starts and everything works just fine.

I'm not trying to play any sound yet, just FMOD initialization for now.

Thanks in advance.
