Hello,
I'm trying to embed FS in a C application where I should have to restart
the whole stuff (core) in one process/thread, however it crashes. I
assume, something is not freed up before the new startup. I've used
mrene's fshost example to reproduce the issue:

Any idea what should I add to free up everything after shutdown and lets

Thanks in advance,
