[temp.inst]/2:

    Unless a class template specialization is a declared specialization,

    the class template specialization is implicitly instantiated when

    the specialization is referenced in a context that requires a

    completely-defined object type or when the completeness of the

    class type affects the semantics of the program.



[temp.inst]/3:

    The implicit instantiation of a class template specialization causes

    (3.1) -- the implicit instantiation of the declarations, but not of the definitions, of

        the non-deleted class member functions, member classes, scoped member enumerations,

        static data members, member templates, and friends; and

    (3.2) -- the implicit instantiation of the definitions of deleted member functions,

        unscoped member enumerations, and member anonymous unions.



[temp.inst]/4:

    Unless a member of a templated class is a declared specialization, the specialization

    of the member is implicitly instantiated when the specialization is referenced in a

    context that requires the member definition to exist or if the existence of the definition

    of the member affects the semantics of the program; in particular, the initialization

    (and any associated side effects) of a static data member does not occur unless the

    static data member is itself used in a way that requires the definition of the static

    data member to exist.

Таким образом, по стандарту CrtpBase<B>::x не должен быть инициализирован, поскольку он нигде не used in a way that requires the definition of the static data member to exist. Правильные компиляторы (gcc и clang) это понимают и компилируют код, а вот Visual Studio зачем-то пытается инициализировать CrtpBase<B>::x и нон-конформно ломается.

Comparing structs with, let's say, memcmp, does not work,
 as you end up comparing the "unspecified" padding bytes as well — you must compare member-by-member.

While writing this post, the author observed that some verions of GCC (experimentally, >= 4.7, < 8.0) do not zero padding if an empty intializer list is passed, under certain a certain code pattern; if an entire struct (i.e. sizeof(STRUCTNAME)) is subsequently memcpy'd after assigment of its members, and this intermediate buffer is what is used by the code going forward. This appears to be based on how optimization passes interact with GCC's built-in memcpy, since passing -fno-builtin-memcpy returns the behavior to the expected.
