+/* PR debug/5770
+   This testcase failed at -O -g because the following constants
+   were optimized away since they were never referenced, but
+   since they are variables with initializers, rtl_for_decl_location
+   run expand_expr on their initializers and returned it.
+   This lead to references to constants which were deferred and thus
+   never emitted.  */
