If you are using the above formulation, then the reference is not initialized until runtime. Due to order of initialization issues, you could end up indirecting through an uninitialized reference and crash even before you hit main().
Sorry, could you give me any example such that type const &name = get_static_local<type>(); might cause a crash?
////////// //test.hpp template<typename T> T const & get_static_local() { static S const s; return s; } struct S { int i; }; namespace { S const & s = get_static_local<S>(); } S const & get1(); S const & get2(); //////////// // test1.cpp #include "./test.hpp" S const & get1( ) { return s; } int i = get2().i; //////////// // test2.cpp #include "./test.hpp" S const & get2( ) { return s; } int j = get1().i; int main() { return 0; } Compiles and links just fine, crashes and burns even before entering main(). -- Eric Niebler Boost Consulting www.boost-consulting.com The Astoria Seminar ==> http://www.astoriaseminar.com
