Memory leak when using IShellItem plus BindToHandler

Question

I write this code that iterates over all files on the desktop, its working correctly, however, the memory keeps increasing constantly.

I'm already using CComPtr to automatic manage the memory of these pointers, i'm trying to figure out whats leaking.

The unique place that with some items i get error is at pItem->BindToHandler

the error are:

E_NOINTERFACE No such interface supported. HRESULT_FROM_WIN32(ERROR_RESOURCE_TYPE_NOT_FOUND) : The specified resource type cannot be found in the image file.

When i comment pItem->BindToHandle the memory stops growing, what i'm missing?

    if (pItemList.empty())
    {
        CComPtr<IShellItem> pItem = NULL;
        hr = SHCreateItemFromParsingName(filePath.c_str(), NULL, IID_PPV_ARGS(&pItem));
        if (FAILED(hr))
        {
            std::wcerr << L"SHCreateItemFromParsingName failed with HRESULT: " << hr << std::endl;
            return;
        }
        pItemList.push_back(pItem);
    }

    for (const CComPtr<IShellItem>& pItem : pItemList)
    {
        CComPtr<IPropertyStore> pPropertyStore;
        HRESULT hr = pItem->BindToHandler(NULL, BHID_PropertyStore, IID_PPV_ARGS(&pPropertyStore));
        if (FAILED(hr))
        {
            //std::wcerr << L"BindToHandler (BHID_PropertyStore) failed with HRESULT: " << hr << std::endl;
