A little more reduced:
template struct c { obj data; };
struct r {};
template obj g(const obj &arg);
template
auto g(const c & arg)
-> c(arg.data))>
{
return c(arg.data))>{};
}
int main()
{
c array

Here is the full on reduced testcase (the previous one was wrong):
template struct Container {
obj data[1];
};
template struct Recursive {};
template obj function(const obj &arg)
{
return obj{};
}

Reduced further:
#include
template struct TypeMapper { static const int NestLevel =
T::NestLevel; };
template<> struct TypeMapper { static const int NestLevel = 0; };
template struct Container { obj data;

Signature of fail in 8.0.0 (head) is:
^~~~
prog.cc: In substitution of 'template Container(arg.data[0]))> function(const Container&) [with int N = 1;
obj = ]':
prog.cc:43:101: recur

Just an update:
Still fails in G++ 7.1.0 and in 8.0.0 (head) on Wandbox.
Still passes in Clang 4.0.0 and 5.0.0(head).

p.s. in case anyone is wondering this recursive construct is
a simplification of a construct I'm using in an expression
template framework, so this is not simply a convoluted test case.
Rather, I distilled th
