The following testcase triggers an ICE since GCC 4.0.0:
==============================================
template<template<int> class A> int A<0>::i;
==============================================
bug.cc:1: internal compiler error: in cxx_incomplete_type_diagnostic, at
cp/typeck2.c:426
Please submit a full bug report, [etc.]
Before we issued the diagnostic
bug.cc:5: error: `::i' is not a valid declarator
which wasn't too helpful.
Posting a patch soon.
