misc::vec_with_size creates a vector of the provided size and immediately calls vec.set_len(size) on it, initially filling it with uninitialized memory. It then inserts elements using vec[i] = value.clone(). If the value.clone() call panics, uninitialized items in the vector will be dropped leading to undefined behavior.
