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.
