Obviously CFFI doesn't store random stuff in the high bit.  It's meant
to work on Linux to start with, so the idea never even crossed my
mind.  The reason CFFI was mentioned in this thread is that by using
it you can call arbitrary DLLs, some of which may have the historical
problem --- i.e. assume that all pointers are in the positive half.


A bientôt,

Armin.
