Comment(by strogdon):
I've just completed the testsuite after building vanilla sage-4.7.1.alpha2
from scratch. The patches from tickets #11377, #11244, #9958, #11376 and
#10764 along with the patches of this ticket were used to create a patched
sage-4.7.1.alpha2 spkg before the build. The results are identical to
those reported earlier. There are no segfaults and no Killed/crashed
tests.
On my sage-on-gentoo install on x86 in prefix there no segfaults; however,
I have one Killed/crashed doctest which I didn't have when using
the bug11339a patch.
