Probably the same as: [How to benchmark in-place functions? - #7 by rdeits](https://discourse.julialang.org/t/how-to-benchmark-in-place-functions/36493/7) (reallocation only happens sometimes, so you will rarely capture it from a single `push!` call).

As for why you ran out of memory, I’m not sure–the updated code should use less memory than the original. I would recommend checking carefully that the new and old code actually do the same thing.
