            Bug ID: 99201
           Summary: ICE in tsubst_copy, at cp/pt.c:16581
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: kretz at kde dot org
  Target Milestone: ---

Testcase (reduced with C-Vise from valid code):

template <class, class... F> void test_values_2arg(int, int, F... fun_pack) {
  [] {}(fun_pack()...);
}
template <typename TestF, typename RefF> auto make_tester(TestF, RefF) {
  return [](auto...) {
    [](auto... vs) {
      if constexpr ([&] { reffun(vs...); })
        ;
    };
  };
}
void test() {
  auto __trans_tmp_1 = make_tester([] {}, [] {});
  test_values_2arg<int>({}, {}, __trans_tmp_1);
}


ice.cpp: In instantiation of 'make_tester<test()::<lambda()>,
test()::<lambda()> >::<lambda(auto:1 ...)> [with auto:1 = {}]':
ice.cpp:2:   required from 'void test_values_2arg(int, int, F ...) [with
<template-parameter-1-1> = int; F = {make_tester<test()::<lambda()>,
test()::<lambda()> >::<lambda(auto:1 ...)>}]'
ice.cpp:14:   required from here
ice.cpp:7: internal compiler error: in tsubst_copy, at cp/pt.c:16581
    7 |       if constexpr ([&] { reffun(vs...); })
