            Bug ID: 100282
           Summary: [11/12 Regression] ICE in dependent_type_p, at
                    cp/pt.c:26813
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Keywords: ice-on-invalid-code
          Severity: normal
          Priority: P3

  Target Milestone: ---

g++-11.0.1-alpha20210418 snapshot (g:b412ce8e961052e6becea3bc783a53e1d5feaa0f)
ICEs when compiling the following testcase, reduced from
test/SemaCXX/lambda-expressions.cpp from the clang 11.1.0 test suite:

template <typename... Ts>
void
local_class ()
{
  int { []{ struct ZZ : Ts {}; }... };
}

template // <>
void
local_class<int> ();

% g++-11.0.1 -c xhrah4q6.cpp
xhrah4q6.cpp: In instantiation of 'struct local_class<int>()::<lambda()>::ZZ':
xhrah4q6.cpp:5:29:   required from 'void local_class() [with Ts = {int}]'
xhrah4q6.cpp:10:19:   required from here
xhrah4q6.cpp:5:20: internal compiler error: in dependent_type_p, at
