This might require an understanding of intended program behavior or design to determine whether the value is incorrect."}}, "Potential_Mitigations": {"Mitigation": {"Phase": "Testing", "Description": "Because this function call often produces incorrect behavior it will usually be detected during testing or normal operation of the product.
