It seems that revision 3439 [1] of SDL_mixer broke the music from Pingus 0.7.1 [2].


I noticed it first with data/music/, which sounds all wrong. Reverting the change to pt_UpdateVoices() "fixes" it, but presumably re-introduces the bug that revision 3439 was supposed to fix. I'm afraid I don't have any ideas for how to fix it properly.

I upgraded libmikmod to version 3.1.12 and reverted the patch which caused this bug, which was fixing the following bug:

I've sent e-mail to Brandon, who submitted that patch to see if his bug is fixed by the libmikmod upgrade.

Brandon wrote back with more information on the debian bug:

The newest version of libmikmod still has the bug I reported and made a
patch for.
So if you upgraded libmikmod, and removed my patch, then SDL-mixer
would most likely again suffer from this bug.

I would be happy to help you out. I need to know which libraries I need
for the above functions.

If you want to try to duplicate this yourself:

  1. download and build an older version of penguin command:
  2. run penguin command with the SDL mixer library you want to test

It should segfault 1/4 times on boot. Specifically, whenever
pennight.mod plays, it should segfault. If you were to continue to play
the game, then eventually it should segfault when the music eventually
transitions to pennight.mod.

MOD which sounds wrong with Brandon's patch

I verified that this MOD will not sound correct if Brandon's patch is applied. The pf->numchn is set to 8, but by the end of the song there are 41 voices playing.

Patch for libmikmod fixing both this bug and Brandon's crash

Okay, I tracked down the issue and have a patch for libmikmod that solves both this bug and the crash Brandon was trying to fix.
