repro code

I get the following internal compiler error with g++ 4.8.2 and the attached
repro code:

gcc_ice.cpp: In instantiation of ‘class Foo<float, 5>’:
gcc_ice.cpp:35:28:   required from here
gcc_ice.cpp:28:17: internal compiler error: unexpected expression ‘P_S’ of kind
template_parm_index
  friend void Bar<U, P_S, A_S>::impl (const Foo<U,P_S>& poly);
              ^

This was tested on Arch Linux (x86_64).

Running

  gcc -c -DNDEBUG=1 test.c

on the following code will give an ICE:

  #ifndef DEBUG
  #define NDEBUG  /* Re-define NDEBUG - should warn but not ICE  */
  #endif
  #include <assert.h>


will give an ICE with 4.9:
