                    variable

           Version: 2.8
          Platform: PC

This testcase produces no warnings:

  #include <iostream>
  int main() { int i; std::cout << i; }

This testcase also produces no warnings:

  #include <iostream>
  int main() { int i; if (i) return 1; }

g++ produces -Wuninitialized warnings for both of these.
