Re: How much do we care about small memory leaks?


There are quite a few leaks in the code at present, and every now and then
I go through and try to plug some of them (but I don't find all of them,
that is for sure). 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):
