Mismatch delete

I have program which implements database of peoples and his companies. I have created dynamic array of pointer to class members instead of dynamic array of class members, cause copying is quicker with it.

I have version which works but valgrind shows mismatch delete in destructor (delete db)

CCompany** db;

~CCompanyIndex ( void )
{
    for(unsigned i=0;i<len;i++)
    {
        /*cout<<"dealloc:"<<db[i]<<endl;*/
        delete db[i];
    }
    delete db;
}

CCompanyIndex ( void )
{
    max=1000;
    len=0;
    db=new CCompany*[max];
}

I use also to add

CCompany* newIt=new CCompany(oName,oAddr,cName,cAddr);

So I have tried following code which I consider correct previously

~CCompanyIndex ( void )
{
    delete [] db;
}

But then all memory allocated by adding method is not deallocated.
