--- Comment #7 from Bernd Edlinger <bernd.edlinger at hotmail dot de> ---
This avoids also the _Alloc_hider constructor.
But it still reproduces with gcc-6 and gcc-7.
I have found no way to add __attribute((noinline, noclone))
to the template specialization, that works.
So I did the dirty trick...
It would not have been able to link with gcc-6
because the signature appears to have changed.
So that would have been necessary to do anyway.
Can you try this please?
