Hi,

This bug report is a result of discussion in
https://list.orgmode.org/87v8funovi.fsf <at> localhost/T/#m4da0718c652fe2d9478b050ae8e85f0093645d85

`memory-report--buffers' calls `memory-report--buffer-data' with a fresh
COUNTED hash table in each buffer and then adds up the results.
This is inaccurate when buffer-local values refer to the same object in
memory - the shared objects are counted multiple times in "Total Buffer
Memory Usage".
