The following valid code snippet triggers an ICE since GCC 3.1:
====================================================================
template<template <typename T, typename = T > class U> struct A
{
template<int> U<int> foo();
};
====================================================================
bug.cc:3: internal compiler error: in tsubst, at cp/pt.c:7450
Please submit a full bug report, [etc.]
This is related to PR 30044, but here we have a regression.
