    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.

access
access (access-mode, ref-index)
access (access-mode, ref-index, size-index)

// примеры:

__attribute__ ((access (read_only, 1))) int puts (const char*);
__attribute__ ((access (read_only, 1, 2))) void* memcpy (void*, const void*, size_t);

__attribute__ ((access (read_write, 1), access (read_only, 2))) char* strcat (char*, const char*);

__attribute__ ((access (write_only, 1), access (read_only, 2))) char* strcpy (char*, const char*);
__attribute__ ((access (write_only, 1, 2), access (read_write, 3))) int fgets (char*, int, FILE*);

    В GCC 10 какой-то новый атрибут access появился, чтоб более строго что-то там гарантировать:

    The access attribute enables the detection of invalid or unsafe accesses by functions to which they apply or their callers, as well as write-only accesses to objects that are never read from. Such accesses may be diagnosed by warnings such as -Wstringop-overflow, -Wuninitialized, -Wunused, and others.

    The access attribute specifies that a function to whose by-reference arguments the attribute applies accesses the referenced object according to access-mode. The access-mode argument is required and must be one of three names: read_only, read_write, or write_only. The remaining two are positional arguments.

    The required ref-index positional argument denotes a function argument of pointer (or in C++, reference) type that is subject to the access. The same pointer argument can be referenced by at most one distinct access attribute.

    The optional size-index positional argument denotes a function argument of integer type that specifies the maximum size of the access. The size is the number of elements of the type referenced by ref-index, or the number of bytes when the pointer type is void*. When no size-index argument is specified, the pointer argument must be either null or point to a space that is suitably aligned and large for at least one object of the referenced type (this implies that a past-the-end pointer is not a valid argument). The actual size of the access may be less but it must not be more.
