$ g++ -O -Wuninitialized pr48483.cc
pr48483.cc: In function 'int main()':
pr48483.cc:13:30: warning: 'a.A::b' is used uninitialized in this function

From
<http://gcc.gnu.org/onlinedocs/gcc-4.5.2/gcc/Warning-Options.html#index-Wuninitialized-309>:

  Because these warnings depend on optimization, the exact variables
  or elements for which there are warnings will depend on the precise
  optimization options and version of GCC used.
