Subject: [Bug c++/66153] Internal compiler error in nested template function
Date: Tue, 21 Dec 2021 21:58:02 +0000	[thread overview]
Message-ID: <bug-66153-4-LgWcuUmskI@http.gcc.gnu.org/bugzilla/> (raw)
In-Reply-To: <bug-66153-4@http.gcc.gnu.org/bugzilla/>

--- Comment #10 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
A little more reduced:
template<class obj> struct c { obj data; };
struct r {};
template<int N,class obj> obj g(const obj &arg);
template<int N,class obj>
  auto g(const c<obj> & arg)
    -> c<decltype(g<N>(arg.data))>
{
  return c<decltype(g<N>(arg.data))>{};
}
int main()
{
  c<r > array;  
  g<1>(array);
}
---- CUT ----
Without the guide for the return type, GCC accepts the code. Somehow GCC is
messing up g<N>, Removing the template argument N also allows GCC to accept the
code.
