The girl forgot to mention exception safety on the class A slide, no hire.

The constructor also wasn't tagged explicit.
If B() is noexcept then A() is actually exception safe. The only thing which could happen would be bad_alloc but then v does not have to be deleted any more.
Right, like what happens with the memory allocated for px in situation like below, if new ClassY throws?
A::A() : px(new ClassX), py(new ClassY) { }
