And the leak stays at this memory amount or does it grow over time?

It seems to imply that it is a multi handle that is never freed. It *could* be
a multi handle that's used privately within libcurl by an easy handle (because
it looks like there's a hash there with three entries that also aren't freed).
Does your program ever run a transfer with the easy interface?

If you can, running the code with valgrind will probably give us more details
of where and how exactly the leaks occur.
