Maybe your random number generator sucks? :-)

Can you tell me exactly what options your using to run your pass? I 
assume you're running it with 'opt' like this?

opt in.bc -randomize | llvm-dis

?

Well, you're not saving the output of your pass, it's going to
/dev/null.  Try:

opt -load ... < input.bc > output.bc

And then look at how output differs from input.

If you want to be particularly lazy you can just type M.dump() at the very end
of your pass too.  Then you don't even had to dissamble any bytecode files.
(Assuming M is the name of your Module, and you are doing a ModulePass,
otherwise F.dump() for a FunctionPass with F as the name of the function).
