I believe this already exists, its the ID field of ANYOBJECTFIELDS
defined in global.h.  Each object gets an ID at creation in create.c.
They aren't serialized however, so you presumably get a different ID
each time.  I've never had the urge to use it for anything but it does
get used:

$ cd ../src && grep -e '(->|\.)ID' * | grep -v create.c | grep -v
cscope.out | wc -l
