Hi everyone,

I'm using Lua to extend Moray - a 3D modeller for POV-Ray that runs 
under Windows - but I noticed that, in some situations, Lua calls 
_ALERT (wich has been redefined to pop a MessageBox) and exits.

Well, I can't let Lua exit without giving the user the chance to save 
his/her work. So I would like to know where exactly Lua can call exit
() and how to avoid it.

Of course I'm aware of luaL_opt*, but are there any other places 
where exit() can be called besides argument passing from Lua to C?

For those who want to check this project, visit The source code will be available 
as soon as I have a resonable stable version, without exit()'s!
