Surely a stupid mistake on my part, but why is the first array repeated?
In addition to what Neia said, you shouldn't use pointers to dynamic
arrays. Such things are really hard to allocate on the heap, since new
int[] just makes an array, not a pointer to an array. You're way more
likely to accidentally store pointers to stack variables (as demonstrated).
The only way 2 ways I know of to do it are to a) allocate a
multi-dimensional array, and take it's pointer (e.g. (new int[][1]).ptr)
or b) create a dummy struct with an array in it, and new that:
Struct Dummy { int[] array; }
auto p = new Dummy;
auto ptr = &p.array;
Just use int[][2] a, you will be better off.
