I'm facing a inconsistent behavior with Variant when bool is defined. The below code will return i as 0

typedef boost::variant <int> VariantType;

VariantType variant; int i = boost::get <int> (variant)); // default to 0

If I set a bool in the variant

typedef boost::variant VariantType;

VariantType variant; int i = boost::get <int> (variant)); // this throws fail get

Is it intended behavior?

Yes. A default constructed variant contains the first variant type, so your variant contains a bool, not an int. In Christ, Steven Watanabe
