That any code crashes the compiler is a bug.

 struct Node
 {
 T value; // it seems that template's T have something to do with it
 }
 }
 
 void main()
 {
 Foo!(int) bar=new Foo!(int); // compiler can't create new class
 }

Is this the exact wording of an error message?  Or your speculation of 
what's triggering the crash?

I get 'a.d(6): struct Node no size yet for forward reference'.
Running "gdc (GCC) 3.3.3 (cygwin special)"

When you say 'crashes the compiler', do you mean 'the compiler prints
an error message about the source code, and exits?'

If so, that's not a 'crash'. Don't confuse people by saying it is.
Say what happened. And what version you're running. On what.

If not, pardon me; but it happens a lot. And you should still say what 
happened.

Just because it doesn't crash GDC doesn't mean it doesn't crash DMD.

True.  But I wouldn't call it fair to speculate that the OP's misusing 
the word "crash" in this instance.
