 seems to be causing the ICE in PR 9778. A small testcase is
 ----------------------------
 namespace NS {
   template <int N> void foo ();
 }
 
 template <int N> struct X {
     int m;
     int g () {
       NS::foo<sizeof(m)>();
     }
 };
 
 template class X<2>;
 ---------------------------
 
 Jeffrey, would you mind taking a look? This report seems to be the last 
 that prevents me from building (and then testing again) my library with 
 mainline...
 
 If you are lucky, the fix to this report also fixes PR 9749, see the 
 comment in 9778.
 
 Thanks
   Wolfgang
