This test seems to regress between 5.2 and 5.3.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69098 --- Comment #5 from Martin Sebor --- I looks like it was introduced in r186681. The last good commit before that is r186667, and none of those in between touch the C++ front end. Though the changes in r186681 look very mechanical and not related to templates at all so I'm not sure.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69098 --- Comment #3 from hir...@trash-mail.com --- Your testcase is really quite a bit smaller still – impressive skills! :) Thanks for confirming and since 5.1.0 works for you, on Wandbox and additionally your testcase doesn’t fail locally, I guess I might just have looked at the wrong one of my two installations when I queried the version, perhaps I forgot to prepend '.\' or something like that.

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