I’ve a problem with Mix_OpenAudio in SDL 2.0, that makes crash Windows kernel.
If i compile with GCC, no problems.
If i compile with GDB, the game i’m developping crashes.
I’m under Codeblocks 16.0.1.
I’ve tried both MinGW that comes with it, and TGM_GCC, it’s the same thing.
This is my source code.
I’ve tried to enable, disable command lines, it’s really Mix_OpenAudio that makes GDB crashes.
Code:
// load support for the OGG sample/music formats
int flags = MIX_INIT_OGG;
int initted = Mix_Init(flags);
if((initted & flags) != flags) {
printf(“Mix_Init: Impossible d’initialiser le support ogg !\n”);
printf(“Mix_Init: %s\n”, Mix_GetError());
return 1;
}
// TODO: r??soudre le bug qui emp??che GDB de fonctionner (ici !!!)
if(Mix_OpenAudio(44100, MIX_DEFAULT_FORMAT, MIX_DEFAULT_CHANNELS, 2048) < 0) {
fprintf(stdout,"Impossible d'ouvrir Mix_OpenAudio: %s", SDL_GetError());
return 1;
}
// Allouer 16 canneaux de mixage
Mix_AllocateChannels(16);
And the error :>
In RaiseException () (C:\WINDOWS\System32\KernelBase.dll
Are you calling Mix_OpenAudio “after” you’ve called SDL_Init? Does your SDL_Init include SDL_INIT_AUDIO | SDL_INIT_EVENTS? What are you passing to the SDL_Init?
Are you compiling the SDL Mixer or are you using the DLL’s?
I have not encountered any problem using the mixer and I compiling for Windows, Linux and Android. For Windows I use all the provided SDL DLL’s. Life is simpler that way.
The sound settings I use are…
frequency=“44100” sound_channels=“2” mix_channels=“8” chunksize=“1024”
Just an FYI. A lower chunk size and a higher frequency provides lower sound latency. I’ve noticed this mostly in Windows.
Do you really need “16” mix channels? I’d try 8 to see if that is related to your problem.
I’m under Windows 10 (x64), using Codeblocks, so i must compile with Mingw32 and i have the 32 bits dll’s in my project directory.
I’ve added the include & lib directories from the i686 directory, and when i compile in normal mode, it works perfectly.
Only GDB dislike my program.
I’ve seen this bug on google, but nobody seems to know where it comes from.------------------------

When I build and run in Linux, I use Netbeans as the IDE and it uses GDB. Everything works fine.
For Windows, why not just use the free community version of Visual Studio? It has all the features you’ll ever need. That’s what I do. Chances are there’s a problem with the debugger since it was ported to Windows.
You’ll need to add SDL_SetHint(SDL_HINT_WINDOWS_DISABLE_THREAD_NAMING, “1”); BEFORE calling any SDL initialization functions, including Mix_Init(…) (even SDL_INIT(SDL_INIT_TIMER); will trigger it)
I believe this is because SDL calls RaiseException when the GNU debugger is attached under windows, it appears versions of GDB greater than 7.11 (?) will trigger on this exception, maybe because it doesn’t support exceptions that can continue?
