  ****************************************************************
  Under rare circumstances, when compiling with OPT(2|3), the
  Fortran compiler may generate incorrect code. It's not possible
  to be more precise about the circumstances, as these are depend-
  ent upon environmental factors such as internal storage alloca-
  tion and structure. The error arises when the Fortan compiler
  mistakes a temporary for a constant in a dictionary entry. The
  symptoms are such that a bogus constant may be incorrectly
  generated and used, instead of a QTEMP (temporary variable).
  

Problem conclusion

• The VS Fortran compiler has been changed so that it cannot
  mistake a temporary for a constant in a dictionary entry.
