* @brief Get variables 0 and 1 from current activation records and

*
* Assumptions:
* - There are at least two variables present.
* - They are indeed both integers
*
* If the assumptions are incorrect, assertions will fire and/or
* bad stuff will happen.
*
* NOTE: This function should not be externally callable!
