[Bug tree-optimization/15879] New: Bad message "struct$member may be used uninitialized"

["bangerth at dealii dot org" <gcc-bugzilla at gcc dot gnu dot org>]

This is actually a progression, since for this case 
------------- 
struct X { int a; }; 
 
int f() { 
  X x; 
  return x.a; 
} 
------------- 
we did not get a "may be uninitialize" warning before. We get now: 
g/x> /home/bangerth/bin/gcc-3.5-pre/bin/c++ -c x.cc -O2 -Wuninitialized 
x.cc: In function `int f()': 
x.cc:5: warning: 'x$a' is used uninitialized in this function 
 
However, I believe that this should read that 'x.a', not 'x$a' may be 
used uninitialized, keeping with the member access operator convention 
of at least three languages supported by gcc.
