Understood. I built that emacs with -O2 and without " --ena= ble-checking=3D'yes,glyphs' --enable-check-lisp-object-type" a= s it's my daily driver version.

=C2=A0
If you can reproduce this problem, please post the recipe; otherwise I
don't see how this could be of any use.=C2=A0 Too bad.

I'll work on getting a recipe.

Why isn't there a -g3 in the compiler switches?=C2=A0 AFAIK, the defaul= t
configuration supplies it.

Yes, I did not a= dd that switch; I do that in my debug builds.
=C2=A0
=C2=A0 Did you specify CFLAG= S at configure time?
If so, please add -g3 to the switches, and I suggest to use -Og,
not -O2, for better debuggability.

Will= do.

Did you merge the harfbuzz branch with master, so there's no pdumper in your build?=C2=A0

Actually, sorry for t= hat 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= .
=C2=A0
If not, why do I see CANNOT_DUMP in the list of
features?

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

I'll try to get a recipe.
