      fix a memory leak in basic LTL simplifications · a9fc213a
      Alexandre Duret-Lutz authored
      When something like XFa & FXa is reduced, the subformulae XFa and FXa
      are both rewritten separately to XFa, and then the vector of arguments
      of the And operators, [XFa,XFa], is passed through a specialized loop
      that searches of the form X(...) that can potentially be simplified with
      some other terms.  This loop converts the vector [XFa,XFa] into the set
      {XFa,XFa}={XFa} and forgot to deal with the case where the insertion
      would actually not add an existing subformula.
      
      * src/ltlvisit/simplify.cc: Fix the code for Or, and And.
      * src/ltltest/reduc0.test: New file, to test it.
      * src/ltltest/Makefile.am (TESTS): Add it.
      * src/ltltest/reduccmp.test: Add an extra test that does not
      trigger the bug (because reduccmp.test uses more than basic
      optimizations, and the implication-based simplifications are
      already able to detect that XFa and FXa are equivalent).

      Add an option for nondeterministic monitor.
      * wrap/python/ajax/spot.in: Honor the new option, and rewrite the
      monitor production using postprocessor.

      Fix two memory leak reported by Sonali Dutta. · c8925994
      Alexandre Duret-Lutz authored
      * src/tgbatest/ltl2tgba.cc: Calling tgbatest/ltl2tgba -M -O (which
      makes no sense, but that is no reason) used the "minimized" variable
      for two automata, overwriting one.
      * wrap/python/spot.i: The python bindings did not know about
      sba_explicit automata, causing memory leaks, and complaints from the
      bdd_dict.
