Version is reported as GNU Emacs 28.0.50 (build 1, x86_64-pc-linux-gnu, X toolkit, cairo version 1.16.0, Xaw3d scroll bars) On Wed, 22 Dec 2021 at 13:30, Lars Ingebrigtsen wrote: > Paul Pogonyshev writes: > > > You need any profile that involves unnamed byte-compiled functions, > > i.e. lambda in code.
