            Bug ID: 102799
           Summary: decltype with lambda without body error cause ICE
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: nickhuang99 at hotmail dot com
  Target Milestone: ---

The lambda in outside "decltype" forget to add lambda body which cause ICE
where clang clearly points out this root cause. MSVC++ at least reports error
without crash.


decltype([](decltype([]{}))) gibish;

Forget to mention that obviously this only happens with "-std=c++20" because of
lambda in unevaluated context support.
