hi,
I got sth wrong with D 1.033. Is there a bug?

It's the source code compiled with dmd 1.033
-------------------------------------------------------------------------
extern (C) int printf(char *, ...);

class Bar
{
	this()
	{
		printf("Bar.this()\n");
	}
	~this()
	{
		printf("Bar.~this()\n");
	}
	mixin Foo;
};

template Foo()
{
}

int main(char[][] args)
{
	scope Bar bar = new Bar();
	return 0;
}
--------------------------------------------------------------------

But the output is:
--------------------------------------------------------------------
Bar.this()
Bar.~this()
Bar.~this()
Bar.~this()
-------------------------------------------------------------------
The dtor of class Bar was invoked 3 times. Why?

I confirm. Same output for 1.029, 1.031 and 2.017
BTW, scope may be omitted, same result.
