I'm using LUA 5.0.2 at the moment.  I'm fairly sure the crash occurs in
"sweeplist" in lgc.c (I wanted to test for certain but the code is in a
broken state at the moment... sorry).  A possible point was raised by
Matthew Harmon in another thread...

It was suggested in a reply that this would not cause problems as it would
still be GCed.  I mention it again because I also frequently redefine
functions.  Although this should be GCed okay, there might possibly be a bug
here.  As far as I am aware, the function will simply be replaced in the
global table.  In my code, this function is always the same function (i.e.
there are not 3 different functions in 3 different scripts all called
"Run").

Hope this helps,
