Hi,
The code below does not compile.

std::vector<int> ints;
std::map<int, int> m;

std::for_each(ints.begin(), ints.end(), [&m](int x)
{
    ++m[x];
});

It compiles in g++4.6.1. Is this a bug in VC11 ?

With "Disable Language Extensions" set to Yes, the above code fails to compile. If set to No, then the code compiles.


Thanks.
Jagannath.
