Hello,
Today I faced an error saying "Privileged instruction" when shutting down.
I've changed the way of a trainer work (instead of destroying objects and recreating, just hide and display based on the page), and when shutting down I got that error.

Anything that might throw that kind of error?

Perhaps you destroyed an object and referenced it afterwards?
E.g. createForm() creates a form that has it's onClose event set to free on close. So if ce closes and the form has been closed by ce, the form (and all it's components) will point to invalid memory locations

Well my on close function is this
Code:
form.onClose = function (sender) sender.hide();  GLOBAL.OBJECTS.CURRENT_PAGE = 0; stop_render = true; can_update = false; thread_waitfor(thread); sleep (100); closeCE(); end;

current_page --> most pages are checking if the current page is equals to the needed page (so that prevents updates there)
stop_render --> inside of a creatNativeThread function, where it renders stuff on a bitmap so to avoid it from it to render on a object.
can_update --> breaks the loop (while true do .. end)
thread_waitfor(thread) --> waiting for the a local variable thread (which contains thread), the thread was set to not free on terminate;
sleeping 0.1 sec
closingCE()
