[Bug c++/15300] New: name hiding in constructor yields random results

["jaffe at broad dot mit dot edu" <gcc-bugzilla at gcc dot gnu dot org>]

The following code "redefine.cc" (when compiled under g++ 3.4.0 on ia64)
via "g++ redefine.cc":

#include <iostream>
using namespace std;
int main( )
{    int a = 10;
     {   int a(a);
         cout << a << endl;    }   }

prints the value 65535.  When compiled with -O1 you get the value 0.
However, under g++ 3.3.3 one gets the value 10 (at all optimization
levels: -O0 or -O1 or -O2 or -O3).

Is this behavior ANSI-compliant?  I looked at the standard but
couldn't find the answer.
