+// PR c++/10091
+
+// Original synopsis
+// Bug: We were dying because in general, B::a doesn't have enough
+// alignment for us to take its address.  But if the B is C::b, it does
+// have enough alignment, and we should be able to determine that.
+
+// This only failed on STRICT_ALIGNMENT targets (i.e. not i686)
+
+// July 2003
+// packing of non-pods is now only allowed if the non-pod is itself
+// packed. Also only such pods can be reference bound to non-consts
