Re: [Boost-users] [boost::variant] problems with pointers

After much inefficient debugging, I've discovered that adding a pointer type to a boost::variant is a no-no. It appears to get translated into a bool via get<>, which throws a bad_get exception erroneously (at least in my opinion).

The caviots of using a pointer type in variant really needs to be documented! It doesn't appear to be done so now.

I've discovered that wrapping the pointer in a boost::shared_pointer is a solution. But it wasn't obvious.

Hi Jeffrey, f.ex: variant v; int i = 12345; v = &i; cout << *get(v) << endl; double d = 1.2345; v = &d; cout << *get(v) << endl; cout << *get(v) << endl; output is: 12345 1.2345 *exception* Thats exactly what I would expect. Am I missing something? (tested with boost_1_34_beta + gcc 3.4.2) -- Regards, dave
