DMD 0.158 - Compiler endless loop

[John C]

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.

John.
