Looks like UB to me. From the C++ standard:
Note: in particular, a null reference cannot exist in a well-defined
program, because the only way to create such a reference would be to
bind it to the "object" obtained by dereferencing a null pointer,
which causes undefined behavior. (§ 8.3.2, ¶ 4)
There is plenty of stuff out on the net about this; I find this thread
