           Summary: [GSoC] RefCounted (and clear()) doesn't call
                    destructors of members of structs.
           Product: D

Code:
import std.typecons;
import std.stdio;

struct Enclosing {
    Member m;

    ~this() { writeln("Enclosing.~this()"); }
}

struct Member {
    ~this() { writeln("Member.~this()"); }
}

alias RefCounted!Enclosing Test;

int main() {
    Test a;
    a.RefCounted.initialize();
    return 0;
}

Outputs:
Enclosing.~this()
Member.~this()
Enclosing.~this()

The first two destructor calls are because of the call to initialize() which
replaces the internal copy. The third one is called when 'a' goes out of scope.
Unfortunately the destructor of 'a.m' is not called.

This seems to be because of clear():
Code:
int main() {
   Enclosing a;
   clear(a);
   return 0;
}

Output:
Enclosing.~this()
Enclosing.~this()
Member.~this()

The last two calls are when 'a' goes out of scope. The first one is on clear(),
but as you can see it only calls the destructor of Enclosing.

This causes memory leaks in my project, but that's about it. So it's not a
blocker, but it's important for it to get fixed.

The cause is the same as in Issue 5667.
