That's more or less cut&paste from the instructions for a minimal
example. There is no guarantee that the code removed along with the
segfault is responsible for the segfault. But there is a good chance
that you have arrived at a version where the segfault is easier to
diagnose, because we'll be searching for the needle in a quite smaller
haystack.
