The program

union U
{
  struct { int a; }
  struct { int b; }
}

void main()
{
  printf("%d %d", U.a.offset, U.b.offset);
}

outputs:
  0 4

It is a bug or strange D feature?

A bug that I've been about to report for a while, but you got there first.

I found that it only happens with an anonymous inner struct - a predefined struct seems to work fine.  It works if there is only one inner struct and it is put at the end (IIRC) of the union definition.
