gcc/testsuite/g++.dg/ext/attrib5.C

+// There were two related problems here, depending on the vintage.  At
+// one time:
+//
+//    typedef struct A { ... } A __attribute__ ((aligned (16)));
+//
+// would cause original_types to go into an infinite loop.  At other
+// times, the attributes applied to an explicit typedef would be lost
+// (check_b3 would have a negative size).
+
+// First check that the declaration is accepted and has an effect.
+typedef struct A { int i; } A __attribute__ ((aligned (16)));
+int check_A[__alignof__ (A) >= 16 ? 1 : -1];
+
+// Check that the alignment is only applied to the typedef.
+struct B { int i; };
+struct B b1;
+typedef struct B B __attribute__((aligned (16)));
+struct B b2;
+B b3;
+int check_b1[__alignof__ (b1) == __alignof__ (b2) ? 1 : -1];
+int check_b3[__alignof__ (b3) >= 16 ? 1 : -1];
