Forwarding downstream bug: <https://bugs.gentoo.org/show_bug.cgi?id=420257>
Emacs 24.1 fails to build on an amd64 system with x32 ABI [1][2].
During compilation, about 20000 warnings like:
warning: left shift count >= width of type [enabled by default]
warning: right shift count >= width of type [enabled by default]
occur, and finally the build process aborts with a segmentation fault:
if test "no" = "yes"; then \
ln -f temacs bootstrap-emacs; \
else \
`/bin/pwd`/temacs --batch --load loadup bootstrap || exit 1; \
test "X" = X || -zex emacs; \
mv -f emacs bootstrap-emacs; \
fi
/bin/sh: line 6: 27446 Segmentation fault `/bin/pwd`/temacs --batch
--load loadup bootstrap
make[1]: *** [bootstrap-emacs] Error 1
make[1]: Leaving directory
`/var/tmp/portage/app-editors/emacs-24.1/work/emacs-24.1/src'
make: *** [src] Error 2
See [3] for the full build log.
I've attached a one line patch that fixes the problem for me.
AFAICS, Emacs from BZR is not affected.
(Sorry about the bad timing, but x32 support in Gentoo is just
available since a few days.)
