The same thing can happen for unions in c++11. Consider the following:
struct some_struct
{
some_struct() = default;
some_struct(int v) {}
};
typedef union {
int x;
some_struct y;
} a_union_t;
a_union_t z;
This creates a DW_TAG_typedef with children. I propose to extend the
candidate patch to unions:
