           Summary: ICE with int templates
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: weiss at sztaki dot hu
                CC: gcc-bugs at gcc dot gnu dot org

The following example causes an ICE:


gonzo:~ # cat foo.cc
template <int A, int B, int C, bool D=(A<B)>
struct a
{
  enum { value = D? A+B: A+C };
};


template <int A>
struct b
{
//   enum { value = a<A,A,A>::value };  // compiles
//   enum { value = a<A,1,A>::value };  // compiles as well
//   enum { value = a<1,A,A>::value };  // compiles as well
  enum { value = a<1,1,A>::value };  // ICE
};


int main()
{
  return b<1>::value;
}
