--- Comment #1 from Daniel Krügler <daniel.kruegler at googlemail dot com> ---
Your definition of operator!= for the allocator test_alloc violates the
allocator requirements, which impose that != behaves the same as the negation
of == (see Table 28 — Allocator requirements, [allocator.requirements]). This
violates causes undefined behaviour. Therefore it seems to me as if this is an
invalid bug report.
