> Dodji, is there any reason not to apply this fix to 4.5 as well?

I was waiting to see how the initial fix would behave in 4.6 and it felt
below my radar.  But then PR c++/46824 hinted for a better fix for this
issue.  So I am backporting the revert of PR c++/42260 and the fix of PR
c++/46824 instead.

I have tested it on x86_64-unknown-linux-gnu aginst 4.5
