Maybe you are right. I said that because clang was requiring it but gcc-4.7 accept the default constructor as a constexpr. clang-darwin.compile.c++ ../../../bin.v2/libs/thread/test/test_so.test/clang-darwin-3.2xl/debug/threading-multi/test_so.o ../example/test_so.cpp:19:31: error: default initialization of an object of const type 'const array<int, 5>' requires a user-provided default constructor constexpr array< int, 5 > arr; ^ ../example/test_so.cpp:21:12: error: use of undeclared identifier 'a' return a.get(); Best, Vicente
