It looks like R is trying to run with the readline history facilities
started. It shouldn't do this when you are running under ESS.
One quick fix might be to install a terminfo entry for the "emacs"
terminal type but I'm not sure how you do that.
I had thought that when ESS started the R process it should send the
-noreadline flag to it. From the R manual page
The following options are present to support the use of R
from other programs. In particular, the -noreadline
option exists so that R can be run under emacs(1) and
xemacs(1) using ESS.
Turn off the use of the readline(3) command line
If R is getting the -noreadline flag properly then my guess is that
the call to initialize the readline library (probably in
$RHOME/src/unix/system.c) is not being protected by an if statement
that checks for this flag.
Earlier I reported a problem in $RHOME/src/unix/system.c that some
ifdef's were checking for HAVE_READLINE_HISTORY_H but that variable
was not being defined by the autoconfigure script. I'm not sure if
that has been corrected yet.
When I was looking for those definitions I noticed the
autoconfiguration on the version I compiled for Debian Linux 2.0 does
not set HAVE_READLINE but that version on Debian Linux 1.3 does. This
looks like another autoconfigure problem.
