@Ann, if my understanding is correct, the goal of this rule is not to prevent using increment({plus}{plus}) and decrement(--) operators in arguments to function calls but:
* to track function calls with several occurrences of the same variable and in one case application of the increment/decrement operator to this variable.
\[~freddy.mallet] I had originally tried to narrow the portion of the CERT rule I was covering, but expanded to cover more of the scope because original attempt was unclear. FYI, the rest of the scope of the CERT rule is covered by RSPEC-881.
