  12  ** \brief A simple test for SmtEngine::resetAssertions()
  13  **
  14  ** This program indirectly also tests some corner cases w.r.t.
  15  ** context-dependent datastructures: resetAssertions() pops the contexts to
  16  ** zero but some context-dependent datastructures are created at leevel 1,
  17  ** which the datastructure needs to handle properly problematic.
