8555	Variant, Implicit Conversions and C++11	Bryan Catanzaro <bcatanzaro@…>	Antony Polukhin	"With c++11 enabled on g++, the following code compiles on Boost 1.48.0, but not on Boost 1.53.0. It appears the machinery choosing construction method thinks I'm trying to convert from a convertible to an int, rather than from a convertible to a my_variant. If I disable c++11, this code compiles with Boost 1.53.0.

Here's the error:
/home/bcatanzaro/boost_1_53_0/boost/variant/variant.hpp:1574:9: error: no matching function for call to ‘boost::variant<int>::initializer::initialize(void*, std::remove_reference<convertible&>::type)’

And here's a reproducer:

#include <boost/variant.hpp>

typedef boost::variant<int> my_variant;

struct convertible
{
  operator my_variant() const
  {
        return my_variant();
  }
};

int main()
{
  my_variant y = convertible();
}
