Hello,

cc1plus.exe crashes (together with Windows prompt "Program has stopped
working...") while compiling the following code (if it is of any use):

#include <functional>
using std::function;
typedef function<int (int)> int_int_f;

int_int_f a = [] (int x)
{
    return x + 3;
};

function<int_int_f (int_int_f)> b = [] (int_int_f f)
{
    return [=] (int x)
    {
        return f(x) * f(x);
    };
};

int main()
{ }

Command line:
g++ -std=c++0x -Wall crash.cpp

Compiler produces no warnings or errors.

Using GCC 4.6.0 20110205 on Windows Vista (32bit).
