with the wrong allocator.
There are other less invasive solutions, such as having the mechglue

buffer address to find which provider's release_buffer entry point to
call. This is something I've wished to avoid, but Windows makes me
sad enough about the common allocator approach that I'd consider it.
Let's see what Jeff says about the configurable GSS allocator DLL idea
-- that'd be the least disruptive approach for you at this point,
