Understood. I built that emacs with -O2 and without "
--enable-checking='yes,glyphs' --enable-check-lisp-object-type" as it's my
daily driver version.

I'll work on getting a recipe.

Why isn't there a -g3 in the compiler switches?  AFAIK, the default

Yes, I did not add that switch; I do that in my debug builds.

Will do.

Did you merge the harfbuzz branch with master, so there's no pdumper

Actually, sorry for that confusion. I realized that I had the
--with-harfbuff switch since when I tried the harfbuff branch, but forgot
to remove that from my build script.

This was built using the latest master (i.e. with pdumper and no harfbuzz).

I'll try to get a recipe.
