internal compiler error on lambda expression

[samuelpmish]

the regular C++ code

#include <cstdio>

template < int m >
void foo() {
    printf("m: %d\n", m);
}

int main() {
    int m = 2;
    [&](){ foo<m>(); }();
    return 0;
}

should fail to compile, as m is not a constant expression, but circle experiences an internal compiler error:

  error: example.cpp:10:16
  internal compiler error: cannot access data members of closure at compile time
      [&](){ foo<m>(); }(); 
                 ^
Compiler returned: 1

Oddly enough, nvcc also dies on this code snippet and fails to emit an error message before doing so.

circle still provides a helpful error message to help diagnose the problem before it hits the ICE-- so better than nvcc in that respect!
