[Solved] Manipulating memory returns invalid pointer error (C++)

MegapolisPlayer Asks: Manipulating memory returns invalid pointer error (C++)
I have a class called Array with a copy constructor and a copy assignment operator (which is not important currently).

Array has a few member variables:

• mArray is the internal raw array
• mSize is the amount of elements
• mReserved is the amount of currently allocated space
• mMemoryAllocated is a boolean value which determines if any memory has been allocated by the class.

The class works normally, but when I copy it i get an error, specified below.

Here is the code:

Copy c.:

template<typename tType>
    Array<tType>::Array(const Array& aOther) noexcept {
        this->mArray = nullptr;
        this->mSize = 0;
        this->mReserved = 0;
        this->mMemoryAllocated = false;
        
        if(aOther.mMemoryAllocated) {
            this->mArray = (tType*)malloc(aOther.mReserved * sizeof(tType)); //pointer invalid???
            if(this->mArray == nullptr) {
                //my custom error handling
            }
            for(U64 Id = 0; Id < aOther.mSize; Id++) {
                this->mArray[Id] = aOther.mArray[Id];
            }
            this->mSize = aOther.mSize;
            this->mReserved = aOther.mReserved;
            this->mMemoryAllocated = true;
            return;
        }
    }

Destructor:

template<typename tType>
Array<tType>::~Array() noexcept {
        if(this->mMemoryAllocated) {
            //call destructors
            for(U64 Id = 0; Id < this->mSize; Id++) {
                this->mArray[Id].~tType();
            }
            free(this->mArray);
        }
}

Test code:

Array<int> TestArray;
        
TestArray.Add(56);
TestArray.Add(58);
TestArray.Add(66);
TestArray.Add(78);
TestArray.Add(560);
TestArray.Add(690);
TestArray.Add(456);
TestArray.Add(59);
TestArray.Add(57);
TestArray.Add(69);
TestArray.Add(75);
TestArray.Add(555);
TestArray.Add(699);
TestArray.Add(999);
        
{
    Array<int> TestArray2 = TestArray;
        
    TestArray.ShiftRight(3, 2);
    TestArray2.ShiftRight(3);
    TestArray2.Add(56); //crashes here as well
            
    IO << TestArray << "\n";
    IO << TestArray2 << "\n";
            
} //test array 2 issues

The error I'm getting is munmap_chunk: invalid pointer.

I have tried replacing the for loop with memcpy, but to no avail.

I have also tried debugging it with gdb, where it always points to either realloc or free calls (confirmed in the call stack)

IO is a wrapper for std::cout with some extra functionality.

I'm using clang(++) 14 on Linux (Mint 21) and the CodeLite 16.4 IDE.
