Subject: alignment: Resolve allocator construction issues on debug

This was related to the source allocator being passed into the
constructor potentially having a different type than allocator being
constructed.

We simply need to provide a constructor to handle this case.

This resolves issues related to the allocator causing debug builds on
MSVC to fail.
