  • The data flow anomalies are:
    • use of an undefined variable;
    • assign a value to a variable more than once without reference such a variable between these assignments;
    • deallocate or initialize a variable before it has been allocated;
    • deallocate a variable before it has been used;
    • assign a new value to a variable reference (pointer) before deallocating the previous one. <bib>martins:2009</bib>, <bib>vincenzi-maldonado:slides:2007</bib>
