Trying to start dwarffortress (from AUR) I get:

$ dwarffortress
Sound devices available:
ALSA Software
OSS Software
Picking ALSA Software. If your desired device was missing, make sure you have the appropriate 32-bit libraries installed. If you wanted a different device, configure ~/.openalrc appropriately.
Perfect OpenAL context attributes GET
Loading bindings from data/init/interface.txt
data/sound/song_title.ogg: 3532781 frames requested, 3532781 frames read. Corrupted file?
data/sound/song_title.ogg: Unexpected number of channels: 2097248
terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc

I seached for others who have the same problem and found this:
That looks like a problem I ran into earlier where the sound thread was crashing the program. Did you compile the graphics library yourself?

I ran into a problem after compiling the graphics lib on my 64 bit system. Apparently the header file for the library (libsndfile?) used to open ogg files gives a different size structure if you compile it on a 32 bit machine than if you compile it with -m32 on a 64 bit machine. This causes the elements in the structure to be shifted by 32 bits, causing DF to think there are a lot of channels in the audio ("Unexpected number of channels: 2097248") instead of a lot of frames or whatever, and eventually causes a segfault. I "fixed" this on my copy by changing the header file for that sound library so that the element in the structure causing the problem would be the same size (uint64_t?). I'm not at that PC at the moment, so I may not have everything exactly right.[/quote]

I believe the current lib32-libsndfile on multilib may be affected by this same problem.

Additional info:
lib32-libsndfile 1.0.21-3 (multilib)
dwarffortress 0.31.12-1 (AUR)

Steps to reproduce:
start dwarffortress (AUR)
This task depends upon

I forgot to mention: it was working flawlessly before I started using multilib.

I tested both but it seems neiter one fixes the problem.
Exactly the same error as before. :(
How about you, does if work for you?

Not that it needed but just a 2nd tester.
Neither package resolves issue here either.
FWIW Im NOT using AUR package but archgames package.
