           Summary: gcc rejects true ? [](auto) noexcept {} : [](int) {}
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++

int main() {
  true ? [](auto) noexcept {} : [](int) {};
}

GCC-trunk only accepts the above code in C++14 but rejects it in C++17/20.
