# A simple test for SolverEngine::resetAssertions()
#
# This program 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 leevel 1,
# which the datastructure needs to handle properly problematic.
