Do you mean "writing side"?

Just kill the translator process.

It is very hard for me to judge what is in fact happening when you say "the
whole system hangs".  There are just too many things that you could mean by
this and too many ways you could be misconstruing whatever you are seeing.

What is an infinite root?  Do you mean an infinite loop?

You have not given enough detail about the situation to judge.  As a rule,
always include the actual output from a program that you are trying to use,
rather than paraphrasing or otherwise characterizing what you saw.  No
offense intended, but if you already knew which observable details
mattered, you wouldn't have to ask us for help, so assume you don't know.
