Created attachment 6412 [details] Source code (-save-temps)
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.
Working on a fix.
