           Summary: [4.6 Regression] [C++0x] ICE: std::sort chokes on
                    simple lambda function
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: erik.sandbraaten@gmail.com


The following code test.cc :

#include <algorithm>
#include <vector>

int main()
{
    std::vector<int> vec;

    std::sort(vec.begin(), vec.end(), [](int& t1, int& t2) {return t1 < t2;});

    return 0;
}

Results in:
