Interesting C99 appearances
malloc takes size_t as an argument, so it determines the maximum size that may be allocated.
And since it is also returned by sizeof, I think it limits the maximum size of any array.

What's the most efficient way to erase duplicates and sort a vector?
...explained in my answer, the implementation build a node (including dynamic allocation) for each element from the input sequence, which is wasteful for every value that ends up being a duplicate. There is no way the optimizer could know it could skip that.
