Sounds like a stack problem and returning to never-never land (random
op-codes in un-initialized memory in the simulator) or just the program
running into your .db statements thinking it was code.

OK.  Nope.   That didn't help any.

I am getting infinite looping at addresses beyond the end of my 
generated code (0x17 and 0x117), with errors of "illegal opcode" and 
"illegal instruction" (MUL and MULS)   There are not looping 
instructions in the code.   The last instructionof the code maps to 
0x16.   I am flambasted again.
