Ticket details:

1)Type of arguments for size of array is modified to size_t from int[[BR]]
2)To avoid overflow, way to calculate "requiredMalloc" is modified to [[BR]]
{{{

  double requiredMalloc = static_cast<double>(size1);
                         *static_cast<double>(size2);
                         *static_cast<double>(sizeof(T));
}}}

3)To check the amount of allocated heap in more detail, variables for address should be counted in the "requiredMalloc"
