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;
