Thanks Roger, could you provide an URL to the "rgeos"
bug tracker as a reference ? Having this rationale as a comment
on trac would also be nice. TIA

There is no bug tracker. General practice for all contributed R packages
(almost 8000) is to email the maintainer, whose email is in the package,
and on the archive network package page.
packageDescription("rgeos")$Maintainer
[1] "Roger Bivand <Roger.Bivand at nhh.no>"
This is typically what happens, but in the R-spatial community, it is
equally OK to post on R-sig-geo:
https://stat.ethz.ch/mailman/listinfo/r-sig-geo
which may draw in other comments about user misunderstandings (being an
interpreted language, these do happen).
The rgeos development repo is at:
https://r-forge.r-project.org/projects/rgeos/
but the "lists" there are never used, as the developers all follow
R-sig-geo closely. Questioners may be asked to check attempts to fix
issues by installing from source from the repo; rgeos fails to build on
R-Forge because no GEOS binaries are available there so direct installs
from R-Forge do not work.
In summary - post on R-sig-geo after subscription, and follow the posting
guide with a reproducible example.
In this case as far as I can see, there is no link between the real issue
(use of rgeos through another R package under Windows on CP1252 apparently
switching locale), and the possible valgrind false positive.
valgrind may not be "seeing" all of the behaviour of the R garbage
collector; the 40 bytes are probably the GEOSContextHandle_t r stored as
an R_ExternalPtr and under the control of the R garbage collector
(alternatively something in the errorHandler or the warningHandler). The
handle is properly registered with a finalizer, so unloading the package
on R quit will free the pointer when the GC gets to it.
Thanks for taking an interest in an issue which appears to point somewhere
else - I've asked for a fully reproducible example to see where the locale
switching kicks in.

I would like to file a bug spotted via Valgrind while loading the R
rgeos package. Below are the steps to reproduce it.
This is obviously not a GEOS issue, but should have been sent to the
maintainer of the rgeos package, that is to me. I have resolved the ticket
as invalid.
The identity of "philae" is unknown and untraceable - please contact
me directly including the test script, which wasn't attached to the
ticket.
A minor leakage of 40 bytes isn't a big deal, and its origin isn't clear.
