Description

As prompted in #3419, now assigning packFlag = false in HVectorBase.h

Similar issues also fixed

  • standard_form_valid_ = false in Highs.h
  • initialising HighsInfo::valid = false, which caused valgrind to fail on unit_tests info-md: I wonder why the CI valgrind test didn't fail...
  • using uint64_t total in TestHighsParallel loseTime() which was overflowwing

Now UBSAN_OPTIONS=print_stacktrace=1 build/bin/unit_tests passes
