Package: libncursesw6
Version: 6.4+20231007-1
Severity: grave
Justification: renders package unusable
With libncursesw6 6.4+20231007-1, I get the following issue:
$ screen -dRR mutt /usr/bin/mutt
[screen is terminating]
after a few seconds (or immediately "[screen is terminating]" when
I hit a key). When rebuilding Mutt with debug support, this shows
that Mutt is actually running, but with no output, and I don't know
why it terminates.
Same issue with
screen -dRR mutt sh -c "true; /usr/bin/mutt"
but
screen -dRR mutt sh -c "sleep 1; /usr/bin/mutt"
appears to work. Some kind of race condition?
With
/usr/bin/screen -dRR mutt strace -f -o str.out -s 256 /usr/bin/mutt
the strace output ends with

Downgrading the ncurses packages to 6.4+20230625-2 makes this problem
