+// RUN: not %clang_cc1 -S -emit-llvm %s -fsyntax-only 2>&1 | FileCheck %s
+
----------------



================
Comment at: clang/test/SemaCXX/constexpr-late-instantiation.cpp:9
+  int k = foo<int>(5);           // Ok
+  constexpr int j = foo<int>(5); // CHECK: error: constexpr variable 'j' must be initialized by a constant expression
+}
