* Assert a condition * Make an assertion

* \param expression Expression that must be true * \param expression statement that must be true
*
* Use this macro as if it could always be empty as well.
* I.e. it should not be used with expressions that are relevant
* to the protection against another, untrusted PD or expressions
* that contain mandatory function calls! A good rule of thumb
* is to use it only for the protection of a component against
* a PD-local interface misuse that can't be avoided due to language
* constraints (e.g. inaccuracy of integer ranges).
