             Bug #: 55853
           Summary: [C++11] ICE calling member function of templated class
                    in lambda
    Classification: Unclassified
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: kyle.t.konrad@gmail.com

preprocessed source

This appears to be similar but not identical to
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54604.

Repro case:

#include <map>
#include <functional>

using namespace std;

struct tData {
  double a;
};

template<class DataType>
class MapWrap {
public:

  void Insert(const int& p, const DataType& data) {
    m_[p] = data;
  }

  function<void(const DataType&)> CreateInserter(function<int(const DataType&)>
data_to_int) {
    return [this, data_to_int](const DataType& data) {
Insert(data_to_int(data), data); };
  }

private:
  map<int, DataType> m_;
};

int main(int argc, char **argv) {
  MapWrap<tData> m;
  auto fn = m.CreateInserter([](const tData& d) { return static_cast<int>(d.a);
});
  fn({12});
}

I forgot to mention that adding "this->" to the Insert() call causes
compilation to succeed.
