--- Comment #1 from Richard Smith <richard-llvm at metafoo.co.uk> ---
B is an aggregate, so B{} is aggregate initialization, which initializes the A
subobject from empty braces. That performs value-initialization of an A object,
which does *not* perform zero-initialization first. Replacing 'B{}' with 'B()'
gives 0 as the value of b.a.i, as it should.
