We have mailing lists. 

r-help at lists.r-project.org

would be appropriate. 

You're still not giving sufficient information for anyone to come up
with a sensible reply, though.

Apologies if the tone came out a bit sharp, but allow me to
remind you that the first line of the report form you used reads:

"Before submitting a bug report, please read Chapter `R Bugs' of `The R
FAQ'. It describes what a bug is and how to report a bug."

You do have to realize that from the point of view of improving R, it
simply is not very informative that there is a user who has a problem
which (just?) fitted in available memory in a previous version, but
doesn't anymore.
