What do I do wrong with delete keyword in class destructor?

I have next class:

class IntArray
{
public:
    explicit IntArray(size_t a = 0) {
        this->poi = new int[a];
        this->siz = a;
    };
    ~IntArray() {
         delete[] this->poi;
     };
private:
    size_t siz;
    int* poi;
};

In main something like next code:

IntArray iaa(5);
iaa.~IntArray();

But compiler says that there is a heap corruption in destructor. What do I do wrong?

Aren't you calling it twice? – Evg Jan 09 '20 at 09:34
if you have a question about a compiler error please include the compiler error in the question, though heap corruption rather sounds like a runtime error, also in this case please include the full error message in the question – 463035818_is_not_an_ai Jan 09 '20 at 09:34

*"What do I do wrong?"* -- calling the destructor explicitly. It will be called automatically when `iaa` goes out of scope. So now it's being called twice. – Blaze Jan 09 '20 at 09:34

`iaa.~IntArray();` calling the destructor explicitly is almost always very very wrong. Why do you do it? – 463035818_is_not_an_ai Jan 09 '20 at 09:34
@Timo yes fixed – 463035818_is_not_an_ai Jan 09 '20 at 09:35
