Vic,
The scenario is simple: I redirect func AAA to my code XXX, and then jump
to AAA. Someone else redirects XXX to YYY, which then jumps to XXX, which
then jumps to AAA. Now I exit. XXX is gone! Boom.
One solution is to prevent me from exiting if the func has been redirected
(which is easy to detect). To be super safe I can refuse to run if the func
has already been redirected (assuming the guy might exit without checking).
Cheath has mentioned a library for this problem (which I already knew was
being worked on on another BBS). That would solve it if everyone uses it,
which may be a pipe dream (cynical me). —Mike
