--- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> ---
Confirmed.  The following simplified test case also reproduces the error with
today's top of trunk.  5.1.0 compiles the test case successfully so this is a
regression.

$ cat u.cpp && /home/msebor/build/gcc-trunk-svn/gcc/xg++
-B/home/msebor/build/gcc-trunk-svn/gcc -S -Wall -Wextra -o/dev/null -std=c++14
u.cpp
struct A
{    
  template <int>
  static void (*pf)();
};

template <int>
void foo () {
  (void)A::pf<true>;
}

void bar () {
  foo<0>();
}
u.cpp: In instantiation of ‘void foo() [with int <anonymous> = 0]’:
u.cpp:13:10:   required from here
u.cpp:9:9: error: ‘template<int <anonymous> > void (* A::pf)()<<anonymous> >’
is not a function template
   (void)A::pf<true>;
         ^

u.cpp:9:9: error: ‘pf<true>’ is not a member of ‘A’
