Archie Cobbs (the mpd maintainer) took a look at one of the crash dumps, and concluded that the address list hanging off of the loopback interface (lo0) was corrupted, hence the crash. Recompiling the kernel without IPv6 support seems to prevent the crashes (ie comment out 'options INET6' in kernel config). It is not clear what precisely the problem is, but it seems likely that it's an interaction between mpd and IPv6. Disabling either one appears to be a sufficent workaround to prevent the crashes. If anyone who knows the IPv6 code is interested in looking at the crash dumps, I'll be happy to arrange. Thanks to everone for helping out with this, especially Mike and Archie.
