            Bug ID: 104284
           Summary: [9/10/11/12 Regression] ICE: unexpected expression
                    '<anonymous>' of kind implicit_conv_expr
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dani at danielbertalan dot dev
  Target Milestone: ---

Godbolt link: https://godbolt.org/z/8bTPra5jK

The following code snippet causes an ICE on trunk (commit
3d41939c8799a51b1cd7f4610c06771bf6d52f15), and as far back as on 9.1 with
-fchecking=2:

---
struct EstablishedTiming {
    char m_dmt_id{};
};

auto x = [](auto) { constexpr EstablishedTiming
established_timings3_bytes[]{{}}; };
---

ice1.ii: In lambda function:
ice1.ii:5:80: internal compiler error: unexpected expression '<anonymous>' of
kind implicit_conv_expr
    5 | x = [](auto) { constexpr EstablishedTiming
established_timings3_bytes[]{{}}; };
      |
