Yes, in your code. 
Here is an error message from HP aCC, which explains it:

$ aCC -c junk.cpp
Error (future) 641: "junk.cpp", line 15 # Undeclared variable 'is_ok'. A 
variable with the same name exists in a template base class, but is not visible 
according to the Standard lookup rules (See [temp.dep], 14.6.2(3) in the C++ 
Standard). You can make
    it visible by writing 'this->is_ok'.
         return ( ptr && is_ok() )? 1: 0;
                         ^^^^^           
Fix:

   return ( ptr && this->is_ok() )? 1: 0;

Don't bother: you'll be told the same thing.
