By non-deterministic, I was speaking more to the output of your algorithm.  For example, while DenseMaps based on pointer types may introduce some "non-determinism" in the compiler's specific behavior (i.e., because pointer values may change), the algorithm which uses them should always produce deterministic results.  In this case, the output is non-deterministic, or at least is impacted by factors that should not change it's output (e.g., the endianess of the machine).
