Issue

The issue occurs when you use a function-like macro instead of a function when the two are interchangeable.

Polyspace® considers all function-like macro definitions.

Risk

In most circumstances, use functions instead of macros. Functions perform argument type-checking and evaluate their arguments once, avoiding problems with potential multiple side effects.
