+Subject: c++: designator and anon struct [PR101767]
+
+We found .x in the anonymous struct, but then didn't find .y there; we
+should decide that means we're done with the struct rather than that the
+code is wrong.
+
+	PR c++/101767
+
+gcc/cp/ChangeLog:
+
+	* decl.c (reshape_init_class): Back out of anon struct
+	if a designator doesn't match.
+
+gcc/testsuite/ChangeLog:
+
+	* g++.dg/ext/anon-struct10.C: New test.
