When you file a bug report, Emacs collects important information about
your build and the environment in which you run Emacs.  That already
tells the Emacs developers a lot, and can give ideas regarding the
possible reasons.

Then I suggest to tell in your report how many buffers you have in
that session, and what is their total size.

And finally, I'd encourage you to try to describe your use patterns,
especially regarding operations that could require significant amounts
of memory: visiting large file, loading many fonts, creating large
buffers that don't visit files, etc.  If you can afford keeping notes
about what you did immediately prior to RSS becoming significantly
larger, that is even better.

I don't think the problem is in GC, and the information about that is
part of the info collected by report-emacs-bug anyway.
