[Rd] Reported invalid memory references

From: Ross Boylan <ross_at_biostat.ucsf.edu>

While testing for leaks in my own code I noticed some reported memory problems from valgrind, invoked with
$ R --vanilla -d "valgrind --leak-check=full"

This is on Debian GNU/Linux (testing aka lenny) with a 2.6 kernel, R package version 2.4.1-2. I was running in an emacs shell.

The immediate source of all the problems before I get to the prompt is the system dynamic loader ld-2.5.so, invoked from R. Then, when I exit, there are a bunch of reported leaks, some of which appear to be more directly from R (though some involve, e.g., readline).

Are these reported errors actually problems? If so, do they indicate problems in R or some other component (e.g., ld.so). Put more practically, should I file one or more bugs, and if so, against what?

Thanks.
