Thanks for letting me know! I got enough crash dumps that I finally figured out what's going on with this. I will have a new patch release up in a little bit once I have the fix implemented.

Incidentally the problem is Linux-specific because libstdc++ uses some optimizations for std::sort which aren't robust when using -ffast-math, and that causes it to walk off the beginning of the sorted arrays and silently corrupt memory for a variety of things (MiniAudio, vorbis decoding, crashes in the entity and obstruction grids, etc).
