Description: When starting NVIM 0.2.2-2 within TMUX 2.6-2 tmux crashdumps immediately.

I have submitted a bugreport to tmux,, already about this issue.
This is just a placeholder that this issue exists.

When using NVIM 0.2.2-1 this didn't happen.
A unconfigured tmux, ie. tmux with default settings, but still NVIM 0.2.2-2, produces the same result.

Further details on the tmux Github page.
This task depends upon

Temporarily solution:

<Deleted>, downgraded won't work as neovim 0.2.2-2 is linked against later libraries.

set -as terminal-overrides ',st*:Ss@'

in your tmux.conf

I am raising this issue with ncurses-dev, but also "st", the terminal, to get terminfo entries fixed.

From what I wrote in  FS#57759 :

This issue would be fixed by upgrading the ncurses package to patch 20180224

The changelog for that patch mentions:

- correct Ss/Ms interchange in st-0.7 entry (tmux #1264) -TD

ncurses regularly releases updates to its terminfo database. They are labeled as "Development terminfo source" at

but I get the impression that they are intended as release updates to the most recent ncurses release. This impression stems from a couple comments Thomas Dickey (terminfo maintainer) made:

According to @dx, this issue was fixed in the terminfo database from 2018-02-24. The currently available database at the above URL is from 2019-06-09 (which is the most recent version that runs with the released version of ncurses-6.1).

Therefore, it is my opinion that this bug can be solved in one of two ways:

* Split the ncurses package into two: ncurses-terminfo containing /usr/share/terminfo and ncurses containing everything else. ncurses-terminfo can then be kept up to date with the new terminfo database from the URL above.

* Update the terminfo database and release a new version of this package.

The Makefile includes support for this:

make install.libs install.progs

instead of "make install"
