    // FooBar.cpp by Niels Dekker

    struct Foo
    {
        Foo() {}
        ~Foo() {}
    };

    struct Bar
    {
        Foo myArray[42];
        Bar();
    };

    Bar::Bar() {}

    int main() {}

Command line:

C:\Users\NielsDekker>"C:\\Program Files (x86)\\LLVM\\msbuild-bin\\CL.exe" -cc1
-triple i686-pc-windows-msvc -emit-obj -fexceptions FooBar.cpp
