I've got a fix locally for this, somewhere in the realm of:

---
-  // To place 'obj' behing unwindHeader.
-  enum UNWIND_PAD = (Phase1Info.sizeof + Object.sizeof)
-    % _Unwind_Exception.alignof;
+  // The object being thrown.  Like GCJ, the compiled code expects this to 
+  // be immediately before the generic exception header.
+  enum UNWIND_PAD = (Object.alignof < _Unwind_Exception.alignof)
+    ? _Unwind_Exception.alignof - Object.alignof : 0;

-  static if (UNWIND_PAD > 0)
-    byte[UNWIND_PAD] _pad;
+  ubyte[UNWIND_PAD] pad;
