I have a curses application (written in C++) that during start-up does:
static char linesEnv[32];
static char columnsEnv[32];
/* Init the above vars */
putenv(linesEnv);
putenv(columnsEnv);
linesEnv and columnsEnv contain "LINES=N" and "COLUMNS=N" respectively,
with N being the current terminal dimensions.
Now this sounds like a totally useless thing to do; why would you set
these env vars if they're already set. This is done in order to work
around a bug in an old Solaris version. But on other systems, this
should have no effect.
But with emacs it does have an effect; the application's output is all
messed up. Characters appear in wrong places or entirely missing and
everything is pretty much messed up. I modified the program to not
export the env vars when TERM=eterm (or eterm-color). But in case this
is a bug in Emacs, I'm reporting it here.
I'm using GNU Emacs 23.4.2 built without X support, with Ncurses 5.9 on
Gentoo AMD64. The problem also appears in Emacs 23.1 with X support on
Ubuntu 10.04 (which is the system of the user who reported the problem
to me.)
