You should get a warning with -Wuninitialized at -O1 and above.
In fact I do get one for the following code:
int f(void)
{
int *p;
int &r = *p;
return r;
}

4.0.0 and above's output:
t.cc: In function 'int f()':
t.cc:4: warning: 'p' is used uninitialized in this function
before 3.3's output:
t.cc: In function `int f()':
t.cc:3: warning: `int*p' might be used uninitialized in this function
