It might be interesting (or scary depending on your point of view) to consider what happens if the variable YOUR-POINT is the last reference to the CLOS object here...the finalizer might free the foreign object before mem-aref is entered if the compiler no longer keeps a pointer to the variable. Or more specifically, can this ever be safe? (mem-aref (c-pointer (point0)) ...) __Martin _______________________________________________ Cffi-devel mailing list Cffi-devel@common-lisp.net http://common-lisp.net/cgi-bin/mailman/listinfo/cffi-devel
