           Product: gcc

          Priority: P2

The following piece of (obviously illegal) code ICEs all
versions of gcc since at least 2.95 without a prior error message:
------------- cut----------------
template < typename >
struct unary_transform_modifier ;
template <
class unary_transform_modifier
{
------------- cut----------------
