Basically I recreate a function over and over again, and pretty sure
that my code doesn't cause the leak
while(true)
{

Is there any documentation guideline on how to manage memory with
LLVM? . I am kind of lost here. I tried anything I could but it seems

module and deletes it."
so it should be fine just calling erase.
