      Description

      This rule is a strict implementation of a MISRA (Motor Industry Software Reliability Association) rule. MISRA defines best practices for developing safety-critical software. You can learn more about this rule in the MISRA documents referenced below.

      If you are not concerned with MISRA compliance or with safety-critical software, you might consider using rule S3135 instead ; it targets the same kind of issue for general-purpose software.

      See

      • MISRA C 2004, 12.3 - The sizeof operator shall not be used on expressions that contain side effects.
      • MISRA C++ 2008, 5-3-4 - Evaluation of the operand to the sizeof operator shall not contain side effects.
      • MISRA C 2012, 13.6 - The operand of the sizeof operator shall not contain any expression which has potential side effects
