Incorrect initialization in SharedPtr constructor: what are the consequences

What will happen if the code below is executed? You need to analyze the implementation of the constructor SharedPtr(T* p): whether it correctly initializes the internal pointer and what happens to the passed pointer p.

int* raw = new int;
std::shared_ptr<int> sp(raw);

template <class T>
class SharedPtr {
    int* counterPtr = nullptr;
    T* dataPtr = nullptr;

public:
    SharedPtr() = default;

    SharedPtr(const SharedPtr& other) {
        dataPtr = other.dataPtr;
        counterPtr = other.counterPtr;
        (*counterPtr)++;
    }

    SharedPtr(T* rawPtr) {
        counterPtr = new int(0);
        dataPtr = new T;  // problem here
    }
};
