Mpd tryes to process all possible signals to make clean shutdown. 
Sometimes it can, but sometimes it can't. In such cases it is 
recommended to comment out
   signal(SIGSEGV, SendSignal);
   signal(SIGBUS, SendSignal);
   signal(SIGABRT, SendSignal);
lines in main.c to let it crash and make core dump. Try to do it to get 
core and use gdb to locate crash reason.
