On DMD 0.158, Windows XP, the compiler goes into an endless loop until it runs out of memory when faced with this code:

struct STRUCTA {
  union {
    int a;
    long b;
  }
  STRUCTB c;
}

struct STRUCTB {
  int a;
}

If STRUCTB is defined before STRUCTA, or if STRUCTB is a class or interface, there's no problem. Also, take away the union and it compiles fine.

This did not occur in previous releases.
