 * A simple test for cvc5::Solver::resetAssertions()
 *
 * This indirectly also tests some corner cases w.r.t. context-dependent
 * datastructures: resetAssertions() pops the contexts to zero but some
 * context-dependent datastructures are created at level 1, which the
 * datastructure needs to handle properly problematic.
