            Bug ID: 109823
           Summary: Internal segmentation fault for trailing return with
                    doubly expanded variadic pack
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++

Code

The following code makes the compiler crash if the trailing return with
decltype is added. If the lambda is defined without trailing return, the
program works as expected.
