There exists the possibility that a 'putp' call can be
issued before the 'setupterm' invocation has occurred,
as is reflected in a bugzilla report referenced below.

Strangely, such a SEGV isn't always triggered as logic
would suggest it ought to be. I experienced a fault in
these environments with the associated curses version:
. archlinux, procps-ng 3.3.12, ncurses 6.0.20170429
. fedora-25, procps-ng 3.3.10, ncurses 6.0.20160709
. opensuse-42.2, procps-ng 3.3.9, ncurses 5.9.20140201
. gentoo, procps-ng 3.3.12, ncurses 6.0.20150808
. slackw-14.2, procps-ng 3.3.12, ncurses 6.0.20160910

Whereas under these environments there was no problem:
. ubuntu-17.04, procps-ng 3.3.12, ncurses 6.0.20160625
. debian-test, procps-ng 3.3.12, ncurses 6.0.20161126
. mageia-5.1, procps-ng 3.3.9, ncurses 5.9.20140323

[ as an aside, the expected result in the bug report ]
[ is incorrect and should mention the '1' parameter. ]

[ however, until release 3.3.13 when the '1' becomes ]
[ a valid switch, numbers are not detected when used ]
[ with any switch which doesn't require an argument. ]

[ you're welcome to treat that as a separate bugglet ]
