We have mailing lists.

r-help@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.
