I am now following this strategy here:
https://github.com/jemalloc/jemalloc/wiki/Use-Case%3A-Leak-Checking

I have run emacs -Q for very short time, with:

MALLOC_CONF=prof_leak:true,lg_prof_sample:0,prof_final:true \
LD_PRELOAD=/package/lib/jemalloc/lib/libjemalloc.so.2 emacs -Q

and there are PDF files generated. I also wish to mention that I use 2
dynamic modules, one is emacs-libpq and other emacs-libvterm if that
influences overall. 

You may know easier how to interpret those files and may spot
something. This Emacs session was running just a minute or something.

I am now running new session and will have maybe quite different data
after hours of run.
