print addons: remove invalid use of auto_ptr

Browse Source 
GCC 13 warns that the use of auto_ptr on an array can lead to undefined
behavior, because auto_ptr will use `delete` instead of `delete[]`.

Replaced the use with `std::vector` instead. Since the `data()` member was only
introduced in C++11, the solution uses the [] operator instead to get the
address of the beginning of the array.
