4514 – Regression: Cannot cast from X* to X

This worked in svn r584 (add -m32 switch):
---
void g(void delegate(void*, void*) d);
struct X {
	void f(void*, void*) {}
	void n()
	{
		g(&f); // line 8
	}
}
---
But it breaks on posterior revisions. Well, r585 to r587 don't compile/link (I mean the compiler, not the test program); r588 and r589 compiles (the compiler), but the test doesn't compile anymore, with this error:
t.d(8): Error: cannot cast from X* to X
Maybe some bits of D2 (struct this being a reference?) has been accidentally "ported" to D1.
I didn't tested with D2, though.

Since "this" doesn't appear in the code, I'd doubt that that's the cause.

Compiles fine with r589 D2.

I don't know how the compiler internals deals with this, but the error appears in a method, taking the address/delegate of other method, so "this" exists, even if implicit. And D2 works, which is consisten with this theory.
But again, I'm just talking out of ignorance because I don't know the compiler internals, it was just a hint.

I was going on the assumption that the _internal concept_ of "this" is the same in D1 and D2, and the difference is merely what the _keyword_ "this" means between the two versions.
But you could well ask what obscure thought process the compiler is going through....

The fix for 3706 caused this regression.

Thanks, r590 works fine for me.
