It's definitely related to SSE optimizations. If you tweak CFLAGS to contain "-mfpmath=387" and rebuild dsound the crash goes away, even with all the latest packages.
Confirming, this worked for me. I reported it on the arch side.
Any idea if this is still related to issues in Dsound, or if it's clearly a bug in the arch packages?
