But there are still unasked/unanswered questions: is this a package
that you installed, or is it something that you compiled?   I have
in mind this recent Red Hat bug which shows a problem with applications
building against ncurses6 using the ncurses5 headers.

        https://bugzilla.redhat.com/show_bug.cgi?id=1270534

If it's _that_, then the fix is mostly a packaging issue.
