Yes that would have been my guess.

Bisection points to r241958 but that is nonsense, so I suspect r241944.

--- Comment #1 from Richard Biener  ---
Confirmed, needs -std=c++17, works with GCC 6, fails with GCC 7.

> g++-6 t.C -std=c++17
> g++-7 t.C -std=c++17
/tmp/cc9O32gK.s: Assembler messages:
/tmp/cc9O32gK.s:42: Error: symbol `_Z2fnIKFvvEEvv' is already defined
> c++filt _Z2fnIKFvvEEvv
void fn()

> g++-6 t.C -std=c++17 -c
> nm t.o
 W _Z2fnIKFvvEEvv
 T main

so that it works with GCC 6 might be because of another bug (the instantiation
is missing).
