+Subject: [PATCH] sql: relax constraints on VirtualCursor layout
+
+VirtualCursor::FromSqliteCursor required that VirtualCursor had a
+standard layout, but in fact VirtualCursor shouldn't have a standard
+layout, and the fact that it does with libc++ is a deviation from the
+C++ standard. This change:
+
+1. Relaxes the requirement that VirtualCursor has a standard layout, and
+2. Relaxes the requirement that the sqlite_cursor_ field has to be at
+   offset 0
+
+by use of offsetof() and pointer subtraction. This change both improves
+standards compliance and makes this code build with libstdc++.
+
+Bug: 1380656
