digitalmars.D.bugs - _arguments in constructor

This example should not assert I believe:

===
module main;

class Foo {
   uint args;
   this(...) {
     args = _arguments.length;
     foreach(TypeInfo typeInfo; _arguments) {
       typeInfo.print();
     }
   }
}

int main(char[][] args) {
   auto foo = new Foo(1, 2, 3);
   assert(foo.args == 3);
   return 0;
}
===

I compile with GDC 0.17, om Mac OS X 10.4.4.

The output is:
TypeInfo[]
int
int
int

So it seams that the hidden variable _arguments is included in itself 
for constructors.

So then it is a GDC specific (or perhaps even OS X specific) bug, I better repost it in D.gnu for safe measure. // Fredrik Olsson
