This will *not* happen with the default settings of Visual Studio : it happens when trying to raise the warning level (/we4265 : treat ""misssing virtual destructor"" as an error) Steps to reproduce the problem : - Compile the following program: {{{ #include #include #include int main(int argc, char **argv) { boost::optional name; if (argc > 1) name.reset(argv[1]); if (name.is_initialized()) std::cout << ""Hello, "" << name.get() << ""\n""; else std::cout << ""Hello, world \n""; return 0; } }}} - With the following command line : {{{ cl hello.cpp /Iboost_1_64_0 /EHa /W3 /we4265 }}} outputs {{{ c:\tmp>cl hello.cpp /Iboost_1_64_0 /EHa /W3 /we4265 Microsoft (R) C/C++ Optimizing Compiler Version 19.00.24215.1 for x86 Copyright (C) Microsoft Corporation.
