FWIW a workaround for most valid code is to replace e.g. ignore_index_t,
where v is the problematic NTTP argument, with ignore_index_t.

There might be a dup of this bug already but I can't seem to find it.

--- Comment #1 from LIU Hao  ---
Reduced testcase, also ICEs with GCC 10.3.0 and 11.1.0, but 9.4.0 is fine:

```
template  using a = int;
template  auto b() {
  [](auto... c) { [](a...) {}; };
}
template  using e = decltype(b);
e<1> f;

```


```
$ g++-10 -std=c++17 test.cc
test.cc: In instantiation of ‘auto b() [with int  = 1]’:
test.cc:5:24:   required by substitution of ‘template using e = decltype
(b) [with int d = 1]’
test.cc:6:4:   required from here
