Bug #: 51322
Summary: [C++11] wrong mangling with argument packs
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: marc.glisse@normalesup.org
template<class T> struct Ident { typedef T type; };
template<template<class...>class E,class...F> struct A{typedef E<F...> type;};
typedef A<Ident,int> B;
void f(B){}
compiled with g++ -std=c++0x -c, mangles f as _Z1f1AI5IdentIiEE, that is
f(A<Ident<int> >). Note that if I make E a template<class>class (no ellipsis),
the compiler crashes instead (whereas 4.6 used to give a "sorry"). clang
mangles it as _Z1f1AI5IdentJiEE which AFAICT looks ok.

Jason, are you aware of this mangling issue? Looks like something we may want
to fix rather early.
