I would prefer a single MR for each leak just in case we need to revert
something that gets broken.  I'm fine with grouping related leaks in a
single MR.  There is no need to file an issue report.

My suggestion is that you can either propose a patch in a merge request if you think you know where the memory should be freed and who owns it, or file some issues with the details of the memory leaks if you aren't sure about the memory management. I usually find these when I run under ASAN, and there are several open already (and some more I am needing to open issues for):
