Current mainline GCC generate strage warnings with -O -Wuninitialized options 
if compile testcase:

--8X---------------------------------
#include<map>

struct W {
  static int g(int v) { return std::min(v,0); }
};

struct R {
  R();
  R(int v);
  int m;
};

int main() {
  std::map<int,R> e;
  e[0] = R(W::g(0));
}
--X8------------------------------

Output:
test.cc: In function 'int main()':
test.cc:4: warning: '<anonymous>' may be used uninitialized in this function
test.cc:15: warning: 'v' may be used uninitialized in this function

GCC 4.0.0 compile with same options without warnings.
