Happens here too. I did some gdb work on this (the initial stacktrace isn't too useful because it crashes by trying to do an indirect call via a null pointer). Here's the culprit, the music/sound dtor:

musicsoundst::deinitsound() needs an "if (!functional) return;" guard at the start, in case sound is disabled or failed to link/initialize. |

Although I'm not familiar with the file, I imagine that's similar to the if(!on)return; in the fmod version, so I'll mark this off. I've put it in there and we can see where this goes for 0.31.10. I'm unsure about the larger problems with the libraries overall. |
