Description Mark Millard 2016-12-19 07:55:43 UTC
My attempt to buildworld with devel/amd64-binutils built with with RELRO
enabled resulted in the build stopping for:
(It will be a while before without RELRO is tested.)

(In reply to Mark Millard from comment #0)

Rebuilding devel/amd64-binutils without RELRO and then cleanworld then buildworld
did not change the failing result. It is still:

See Bugzilla 215362 for a likely related libdevdctl build failure for powerpc64's context.
Comment 3 Mark Millard 2016-12-26 08:33:59 UTC
As of head -r310556 (to pick up -r310543's fix) buildworld now
completes, including lib32.

(I've not tested powerpc64 yet: The above is only reporting for
amd64.)
