Bug in SDL_mixer 1.2.7 - reopening does not work

SDL Development
1

Hi,

It seems that SDL_mixer 1.2.7 has problems with reopening the audio. I
have made a short sample application to demonstrate the bug. Both
SDL_Init and Mix_OpenAudio are initing correctly for the first time.

Output with 1.2.7:

az at macbook ~/Programmierung $ cat test_sdlmixer.cpp
/*
generates segfault

    compile with:
            g++ test_sdlmixer.cpp -lSDL -lSDL_mixer -o test_sdlmixer

*/

#include <SDL/SDL.h>
#include <SDL/SDL_mixer.h>

void submain() {
SDL_Init(SDL_INIT_AUDIO);

    Mix_OpenAudio(44100, AUDIO_S16, 1, 512);

    Mix_AllocateChannels(1000);

    Mix_CloseAudio();

    SDL_Quit();

}

int main() {
submain();
submain();

    return 0;

}
