Here's a probably more helpful backtrace:


Program received signal SIGSEGV, Segmentation fault.

(gdb) print PC
$6 = 6422


I noted that PC is always 6422 and remaining_cycles always 28188 when it
crashes...
I also guess the segfault shows up first on the switch because of the
optimization. I guess the real problem is line 1401:

    opcode = bank_readbyte (PC++);




I though maybe this was a 64bit problem in the original (old?) code, but I've
compiled
http://belnet.dl.sourceforge.net/sourceforge/nosefart/nosefart-2.6-mls.tar.bz2 
(which I guess is the original code for nsfdec) which plays the file without
problem on my system.
