/// \brief Finds \c assert() with side effect.
///
/// The condition of \c assert() is evaluated only in debug builds so a
/// condition with side effect can cause different behaviour in debug / relesase
/// builds.
///
/// There are two options:
/// - AssertMacros: AssertMacros: A comma-separated list of the names of assert
///   macros to be checked.
/// - CheckFunctionCalls: Whether to treat non-const member and non-member
///   functions as they produce side effects. Disabled by default
///   because it can increase the number of false positive warnings.
