> Fixed in
[https://github.com/boostorg/variant/commit/d23cdd3502b452231c6c6bc2f2d4298ca24b5650
d23cdd35 develop], will be merged to master branch as soon as the tests
will cycle.
Just for the record: the proposed fix fails the following code:
{{{
#include <boost/variant.hpp>
#include <array>
template<class Node>
struct node1_type;
struct var_type;
using var_base = boost::variant<int,
boost::recursive_wrapper<node1_type<var_type>>
>;
template<class Node>
struct node1_type
{
std::array<Node, 1> children;
};
struct var_type : var_base
{
using var_base::var_base;
};
int main()
{
var_type v1 = 1;
}
}}}
