[Bug c++/43894] New: with -std=c++0x, auto and for loop does not play nice when another variable is involved

["ghodechhap at ghodechhap dot net" <gcc-bugzilla at gcc dot gnu dot org>]

------------------------------------------------------------
#include <iostream>
#include <map>

int main()
{
        std::map<int,int> dummy;
        for(int i=0;i<5;i++) dummy[i*2] = (100-i);

#ifdef BUG      
        for(auto itr=dummy.begin(),int i=0;itr!=dummy.end();++itr,++i)
                std::cout << "i:" << i << std::endl;
#endif

#ifdef WORKAROUND
        auto itr=dummy.begin();
        for(int i=0;itr!=dummy.end();++itr,++i)
                std::cout << "i:" << i << std::endl;
#endif

        return 0;
}
------------------------------------------------------------

$ g++ -std=c++0x -DBUG -o auto.bug auto.bug.cpp
auto.bug.cpp: In function ?int main()?:
auto.bug.cpp:10:29: error: expected unqualified-id before ?int?
auto.bug.cpp:10:62: error: name lookup of ?i? changed for ISO ?for? scoping
auto.bug.cpp:10:62: note: (if you use ?-fpermissive? G++ will accept your code)

$ g++ -std=c++0x -DWORKAROUND -o auto.bug auto.bug.cpp


It should have worked the same in both the cases no?
