Can you see a faulting address? Can you attach a debugger to see what 
happens? QEMU and SIS can attach gdb. With the SIS use the `target 
remote :<port>` command where `<port>` is the port the SIS is listening 
on. Then `load` and `run` should work.

Sure, but I am not a LEON or SPARC user so I am not sure what is 
happening here.
