I see. Well, the general wisdom is that a program should not ever segfault, but
instead gracefully handle the error and exit. Perhaps implement a maximal
recursion depth like zsh does. Also see the first item at
https://www.joelonsoftware.com/2007/02/19/seven-steps-to-remarkable-customer-service/
about permanently fixing reported problems at their core instead of dealing
with user reports and requests time and again.
