           Summary: ICE with int templates and static members, regression
                    from 2.95 and 3.3
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: benko at sztaki dot hu
                CC: gcc-bugs at gcc dot gnu dot org

This example is a brainless reduction of a code I can't understand,
but it compiled so long.  I know no workaround.


arta:~/c/proba$ cat templ_shift1.cc
template <int A>
struct a
{
  static int const value = A - 1;
};

template <int B>
struct b
{
  static int foo()
  {
    return a<L>::value;
  }

  static int const L = a<B + 1>::value;
};


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