How can I use the following c structure from d.
struct Item

struct Group
{
  int i;
  int item_count;
  struct Item items[];

tried defining items[] as both "Item[] items" and "Item* items" 
in d, it compiles okay but gives an error when trying to access 
it.

Here is the error.
object.Error@(0): Access Violation

The D equivalent is:

struct Item {
    int id;
}

struct Group {
    int i;
    int item_count;
    Item* items;
}

The error message you're getting makes me think items is null. 
The lack of function names in the stack trace makes it kinda hard 
to understand exactly what's happening - you can turn that on 
with -g for DMD. Seeing some of the code that uses these structs 
might also help.
