--- Comment #3 from Patrick Palka <ppalka at gcc dot gnu.org> ---
Here's a reduced testcase that ICEs when compiled with -std=c++17 since r7-3599
(when GCC is configured with --enable-checking=yes):
$ cat 95675.C
struct a {};
template <typename> struct b;
template <typename bq, typename br> struct b<bq(br)> {
decltype(bq()(br())) c;
};
struct e {
operator a();
};
b<e (*(e))(a)> d;
$ g++ -std=c++17 95675.C
95675.C: In instantiation of ‘struct b<e (*(e))(a)>’:
95675.C:9:16: required from here
95675.C:4:16: internal compiler error: in build_over_call, at cp/call.c:8945
4 | decltype(bq()(br())) c;
| ~~~~^~~~~~
