You get a warning with -Wmissing-field-initializers (or -Wextra) but it should
be rejected.

The implicity-declared default constructor for A should be defined as deleted.

[class.ctor]/5

If there is no user-declared constructor for class X, a constructor having no
parameters is implicitly declared as defaulted (8.4). [...] A defaulted default
constructor for class X is defined as deleted if:
— [...]
— any non-static data member with no brace-or-equal-initializer is of reference
type,
