APAR status

  • Closed as program error.

Error description

  • Instead of the expected type of "void (*)()", the compiler is
    using the exception-specification as part of the function's
    signature as "void (*)() throw()".  This can cause errors with
    template usage when a function with an exception-specification
    is used as a template type parameter.
    
    
       ==== TESTCASE ====
    
    void f(T sth)
    {
            typedef T t;
    }
    
    void zzz() throw() {}
    
    int main( int argc, char **argv )
    {
            f(&zzz);
            return 0;
    }
    
    
    "test.cpp", line 3.19: 1540-1139 (S) An exception-specification
    can appear only in a function or pointer declaration.
    "test.cpp", line 2.6: 1540-0700 (I) The previous message was
    produced while processing "f<void (*)() throw()>(void (*)()
    throw())".
    "test.cpp", line 7.9: 1540-0700 (I) The previous message was
    produced while processing "main(int, char **)".
    

Local fix

  • Remove exception-specification from function.
    

Problem summary

  • PROBLEM DESCRIPTION:
    Exception specification included during template argument
    deduction.
    
    USERS AFFECTED:
    The problem will appear if a user instantiates a template
    parameter with a function type containing an exception
    specification.
    

Problem conclusion

  • The problem has been resolved.
