State-Changed-Why:
I'm unable to reproduce. Also, when I install screen from pkgsrc,
it is not linked with ncurses. Further, screen is installed without
read permissions, so ldd without becoming root is not possible.

equinoxe:~# ldd /usr/pkg/bin/screen
/usr/pkg/bin/screen:
        -lcurses.7 => /usr/lib/libcurses.so.7
        -lterminfo.1 => /usr/lib/libterminfo.so.1
        -lc.12 => /usr/lib/libc.so.12
        -lutil.7 => /usr/lib/libutil.so.7
        -lcrypt.1 => /usr/lib/libcrypt.so.1

lrwxr-xr-x  1 root  wheel  12 Dec 18 14:06 /usr/pkg/bin/screen -> screen-4.7.0
-r-s--x--x  1 root  wheel  419472 Dec 18 14:06 /usr/pkg/bin/screen-4.7.0

I don't have current running either.

Does the problem still exist for you with the latest pkgsrc?
Can you confirm that /usr/local/bin/screen is from pkgsrc?
Would it be possible for you to try on NetBSD 8.1?

If the problem still exists, please also provide the output
from:
printenv TERM
printenv TERMCAP

I was trying with TERM=screen.xterm-256color

Thanks,

 I still have the problem, but only with bash -- at least things like
 tset, reset, more, jove, vi, etc. no longer cause this error.

 : eddie; echo $TERM
 xterm
 : eddie; printenv TERM
 xterm
 : eddie; printenv TERMCAP
 : eddie;

 Even when I would set TERM=screen.xterm-256color, I had the issue with
 bash, but because tset & co. & other curses things don't have this issue
 anymore in screen, I don't see a reason to keep it open.  Thank you for
 getting back to me -- much appreciated!  Not really possible for me to 
 revert to 8.1 to try as I have already updated to 9.99.13.

State-Changed-Why:
Ok, I'm closing the ticket then.

But I did try to reproduce with bash, and couldn't.
I have bash 5.0.11nb1 on my NetBSD 8.1 system.

When I start screen, TERM gets set to "screen" but
I did also try with "xterm" and starting a subshell.
I also tried with setting SHELL before starting
screen.

Bash is linked against terminfo, in case yours is
different.

equinoxe:~> ldd /usr/pkg/bin/bash 
/usr/pkg/bin/bash:
        -lterminfo.1 => /usr/lib/libterminfo.so.1
        -lc.12 => /usr/lib/libc.so.12
        -lintl.1 => /usr/lib/libintl.so.1

Kind regards,
+ Kimmo
