This is a dup of 7019.
I'm not sure the implicit constructor call is allowed in default argument.

Workaround:

struct Foo
{
  this(int n) { }
  //void opAssign(void* a) { }  // not related to this issue.
}

//void test(Foo foo = null) { }  // ng
void test(Foo foo = Foo(null)) { }  // ok

void main()
{
  Foo foo = null;  // ok
}
