[Bug c++/15701] [3.4/3.5 regression] ICE with friends and template template parameter

[reichelt at gcc dot gnu dot org]

------- Additional Comments From reichelt at gcc dot gnu dot org  2004-05-28 12:08 -------
Confirmed.

Here's a reduced testcase that segfaults since gcc 3.4.0:

===============================================================
template<template<int> class T> struct A : T<0>
{
    void foo();
    template<template<int> class U> friend void A<U>::foo();
};

template<int> struct B {};

A<B> a;
===============================================================

The problem seems to be related to the template template parameter.
If I make T, U, B regular classes, the code compiles.
