    ****************************************************************
    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.
