I read this file and tried to follow it.  At the end of the
bug report there is info on how this instance of Emacs was
configured for building.  Isn't

Configured using:
 'configure -C --prefix=/usr/local/stow/emacs-snapshot
[...]
 --enable-checking=yes,glyphs --enable-check-lisp-object-type
 --with-native-compilation 'CFLAGS=-g3 -O0
[...]

the right result?  Should I disable native compilation?

Sure.  I learned about the C-0 prefix key for C-x C-e to
show unabbreviated output.  I also learned about
so-long-mode, but this line is too long.  I therefore attach
the output as a xz compressed file, because displaying it in
Emacs bogs Emacs down.

Ciao; Gregor
