Is it possible to generate a pool of random D or D inline assembler programs, run them safely?

[Enjoys Math via Digitalmars-d-learn]

Without them crashing the app running them?  Say by wrapping with 
try / catch?

You can assume that I've limited the opcode addresses to the 
program and/or the data section which I'll try to put right next 
to the code.

Reason is so I don't have to make my own VM.

I want to mutate computable functions in a genetic-algorithm 
style, so in order to include the full space of computable 
functions I need a full programming language, or a VM that 
includes conditional jump instructions.

The purpose of it is to make a real-time, short-lived function 
predictor.
