Ah right, I misread the error, it looks like the problem happens when
allocator_traits is instantiated and accesses value_type from the
rebound allocator. Hard to say why that causes an issue without the
compiler, maybe an issue with template aliases. But the workaround I
suggested should still work.

I can't really use rebind_traits without reworking the current
implementation, as the allocator is rebound quite early on, and then
passed as a template parameter.
