module globaldtors;
import std.typecons;

import std.stdio;

struct Foo
{
    struct Payload
    {
        this(int x)
        {
            writeln("constructor called");
        }

        ~this()
        {
            writeln("destructor called");
        }

        this(this) { assert(false); }
        void opAssign(Foo.Payload rhs) { assert(false); }
    }

    private alias RefCounted!(Payload, RefCountedAutoInitialize.yes) Data;
    Data data;

    this (int x)
    {
        data = Data(x);
    }
}

Foo foo;

void main()
{
    /+
     + destructor called <- this should not happen
     + constructor called
     +                    <- where's the dtor call?
     +/
    // foo = Foo(1);


    /+
     + destructor called <- this should not happen
     + constructor called
     + destructor called
     +/
    // auto bar = Foo(1);
}

Uncomment the two assignments individually to verify they print what's in the
comments. Regardless if it's a global or not, a dtor is being called first for
some reason, this looks like a bug.

But if the variable is also a global (TLS/shared doesn't matter), the dtor is
not called on application exit.
