Switch selector expression is constant

The CWARN.CONSTCOND.SWITCH checker finds instances in which the condition of a switch statement is constant.

Vulnerability and risk

A constant condition for a statement typically results in the program's intention not being accomplished, with probable unexpected consequences.

Vulnerable code example

  void foo() {
    switch(3 + 2) { } 

Klocwork flags line 2, in which the switch selector is a constant.
