With the patch at http://gcc.gnu.org/ml/gcc-patches/2010-12/msg01622.html
the testcase above gives:

$ g++4x a.cc -c -Wuninitialized
a.cc: In constructor =E2=80=98A::A()=E2=80=99:
a.cc:4:5: warning: =E2=80=98A::a=E2=80=99 is initialized with itself [-Wuni=
nitialized]
a.cc: In member function =E2=80=98int A::getA()=E2=80=99:
