Some code in this test case is actually only supported in c++17...

cpp11_lambda_functions_wrap.cxx:275:87: error: the type ‘const<lambda(int, int)>’ of ‘constexpr’ variable ‘lambda18’ is not literal
 CONSTEXPR auto lambda18 = [] (int x, int y) mutable TESTCASE_THROW(int) { return x+y; };
                                                                                       ^
cpp11_lambda_functions_wrap.cxx:275:28: note: ‘<lambda(int, int)>’ is not literal because:
 CONSTEXPR auto lambda18 = [] (int x, int y) mutable TESTCASE_THROW(int) { return x+y; };
                            ^
cc1plus: note:   ‘<lambda(int, int)>’ is a closure type, which is only literal in C++17 and later
cpp11_lambda_functions_wrap.cxx:278:89: error: the type ‘const Space1::<lambda(int, int)>’ of ‘constexpr’ variable ‘Space1::lambda19’ is not literal
   CONSTEXPR auto lambda19 = [] (int x, int y) mutable TESTCASE_THROW(int) { return x+y; };
