--- Comment #9 from Richard Biener <rguenth at gcc dot gnu.org> ---
So the issue here is that the allocator state is embedded into the actual
objects
but the C++ standard defines that the old object content becomes undefined
after it is re-used (allocation) or destructed.

openjade is simply non-conforming here.  -fno-lifetime-dse helps.

"Caused" by r222135.

I suppose this warrants some notice in porting_to.html.
