I need more information to be able to reproduce the problem.
The configuration described is apparently not a Red Hat package build,
since it is not listed here:

https://apps.fedoraproject.org/packages/ncurses/builds/

If it had been, and if the problem was not resolved in the two months
since the cited patch, I should be able to reproduce it by the most
recent Fedora build.  Just to be sure, I rebuilt (in my rawhide machine)
this package:

https://koji.fedoraproject.org/koji/buildinfo?buildID=1348376
(ncurses-6.1-12.20190803.fc31).

and did the same for the current pinfo.  While valgrind shows me
some problems from pinfo, none of those are related to ncurses
(see attached log).

fwiw, that's with TERM=xterm-256color, taking care to use the
corresponding ncurses-base and ncurses-term packages.
