[boost] [tribool] short-circuting issue with overloads of operator|| and operator&&

Hi,

I've just used a tribool and a null pointer together in an if-expression:

if (a_tribool || *a_bool_pointer)
   ...

leading to an access violation, because operator || is overloaded for 
tribool and dereferencing the pointer occurs before calling operator || 
instead of short-circuiting the expression.

Is this by design and do I have to access the tribool's 'value' member 
directly?

Thanks,
