Well, in reply to your first email.  without type_check will only turn 
off User declared type's.

EG:

type a(object c)
    if a = 1 then
       return 1
    else
       return 0
    end if
end type

without type_check will cause that type never to execute.  Internal 
Euphoria Type Checks will continue to be processed like usual.
As to the specific problem, try changing the sequence variable to a 
object variable, to prevent it from crashing with a type_check error.  
As to why this is happening, I have no clue, have to see some code 
first, before I can make any assesments. (Like Matt Lewis said)
