The following (IMHO invalid) code snippet triggers an ICE since GCC 4.0.0:

=========================================
template<const int&> struct A {};

template<typename T> struct B
{
  A<T(0)> a;
};

B<const int&> b;
=========================================

bug.cc: In instantiation of 'B<const int&>':
bug.cc:8:   instantiated from here
bug.cc:5: internal compiler error: tree check: expected tree that contains
'decl minimal' structure, have 'indirect_ref'  in decl_linkage, at
cp/tree.c:2191
Please submit a full bug report, [etc.]

Before GCC 4.0.0 the following (not too helpful, if not bogus) error
message was issued:

bug.cc: In instantiation of `B<const int&>':
bug.cc:8:   instantiated from here
bug.cc:5: error: `0' is not a valid template argument
