error: the compiler can assume that the address of '...' will always evaluate to 'true'

• This confusing error has been seen in the following situations ...
  • when passing a pointer, to a function or operator which understands bool but not the pointer type that you’re passing, for example:
      myObject << &object;
  • when returning the dynamic_cast of an address, from a function, when the return type is bool, for example:
      return dynamic_cast<const YourClass*>(&object);
• Some solutions ...
  • Try casting the address using  static_cast<const void*>(&object).
  • Try casting the address using  reinterpret_cast<const void*>(&object).
  • Try creating a variable to hold the cast value, then use that variable instead.
