It could be all manner of things, if it's random then maybe it's writing 
random data to one of the SuperCPU registers which doesn't cause a 
problem on a standard C64 but does when the SuperCPU is plugged in.

Otherwise if it crashes on a particular song at a particular place then 
it might just be that it's doing something that isn't compatible with 
the SuperCPU.

Like undocumented instructions, using RMW side effects for interrupt 
acknowledge.

Trying to find a song that always crashes quickly might help to track it 
down.
