Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When the compiler checks which version of the function call
  to use, a warning message is generated on a candidate function.
  .
    template <typename T2, bool A2>
    Array& operator=( const Array<T2,A2>& x )
    {
      return *this;
    }
  
    template<typename T2>
    Array& operator=( const T2& x )
    {
      return *this;
    }
  .
  The wanring message looks like 1540-724 (W) The non-type
  template argument "1" of type "bool" has wrapped.

Problem summary

•  same as submitter's text
  

Problem conclusion

• Users Affected: Users of multiple template functions with the
    same name with non-type template parameters.
  Problem Description: We were incorrectly generating a warning
    for a conversion on a non0type template parameters during
    selection of viable candidates for overload resolution.
  Workaround: To work around the problem, simply ignore the
    message as it is a warning and will not prevent successful
    compilation
  Expected Errors:
    "ut1.cpp", line 54.13: 1540-0724 (W) The non-type template
    argument "1" of type "bool" has wrapped.
  Problem Conclusion: During selection of viable template
    candidate functions as part of overload resolution, the
    compiler may attemp to instantiate a template function with
    synthesized types to see if it is a viable candidate. Warnings
    should not be generated until the actual candidate is
    instantiated with real types.
