* [Bug c++/42238] New: Missing warning about uninitialized variable

When compiling the following code I expect a warning about usage of
uninitialized variable.
int main(int argc, const char*[]){
do {
int a = a;
} while(1);
return 0;
}
Even when compiled with "-Wall -Winit-self" I get no warning. I have tried with
both g++-4.4.2 and g++-4.2.4 with the same result.
This is a simplification of the case I posted on the gcc-help list
(http://gcc.gnu.org/ml/gcc-help/2009-11/msg00250.html).

a_3 = a_1;
