One of the most fun non-determinism bugs I have worked on was the result of using an associative container with the key type being a pointer (like a std::map<void*, int> or similar), and then iterating over this container.

Since the order and value of dynamically allocated pointers is non-deterministic, this resulted in diverging behaviour at some point.

Better be sure that all your tools used during the build don't do this kind of thing as well.

With ASLR off, the order and value should be identical between runs on the same malloc implementation, as stochastic allocators are not in common use

Not when multi-threading is involved, I would think. That or timing-dependent code making allocations.

[aidenn0]

That's true.
