This code always worked:

struct X {
 union {
   void[] a;
   void[9] b;
 }
}

However, if you remove the union (so that a, b are direct struct members), it
stops working and outputs "Error: integral constant must be scalar type, not
void" (without line number information!). It also stops compiling if you remove
the "a" member.

It also generates a wrong .sizeof for the struct (12 instead of 9*4). Not sure
what exactly is going on.
