(This bug report is for dmd 1.061)

This code:

extern (C) void abort();

struct X {
 union {
   void[] a;
   void[a.sizeof] b;
 }
}

void foo(X b) {
    abort();
}

void main() {
    foo(X.init);
}

Makes gdb output "Dwarf Error: Cannot find DIE at 0x0 referenced from DIE at
0x68 [in module /tmp/test/dr]" when the abort() jumps back into the debugger,
and you request a stacktrace with "bt".

I suspect something is wrong with static void[] arrays.
