OK, done.

Trevor: I marked this bug as closed under the assumption that this
problem is solved, but of course, if it re-occurs feel free to re-open
(ideally while running under GDB in a similar setup, so we get a clear
backtrace again ;-)

Hi,

I had two instances where my emacs was using an excessive amount of memory
(once about 45GiB, and once using 94GiB). I have the memory-profiler report
below. It appears that helm package is the cause, however I was not able to
find out how I can report this issue to helm package maintainers. I would
appreciate it if you can provide instruction for resolving the problem.
Please also let me know if you need more information.

Best regards,

Naveed
