As it will see a release soon, we can probably close this bug then. yes, emacs-cvs-22.0.9999-r1 builds and runs with binutils-2.17. let's wait for the release mark it stabe soon and close this bug.

Does it work? ppc64 is screwed up in general here ... perhaps a tracker bug should be filed so crappy ppc64 flags dont leak into ebuilds everywhere and get lost in the shuffle this is fixed in emacs-22.0.9999-r1, so I think it is OK to add this CFLAGS for ppc64 only in 21.4-r4. once 22.0 is released, stable on ppc64 and the older version removed we won't have any crap lying around, do we? andrew: good work. thanks for this!

That's the way it is. So closing this after CFLAGS additions. > andrew: good work. thanks for this! Yeah! i was talking in more general terms, not just emacs ... like busybox or openssl those added CFLAGS (no longer?) solve the problem for me.. emacs still segfaults for me.

no, same problem. Created attachment 117646 [details, diff] emacs-21.4-ppc64-fix-unexelf.patch Next attempt, patch taken from Redhat/FC6, see <http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=183304>. (This is like poking with a stick in the dark, could someone give me shell access to a ppc64 system?) patch added. Thanks for spotting it, ulm. marking as FIXED.

Greetings from sunny California (In reply to comment #18) > Will this patch hit upstream? Since it was backported from Emacs 22, upstream is aware of it. |
