I've got segmentation fault without any further details. What would I do to reproduce the issue and/or debug?

reproduce... I've no idea. It's your setup. You'll need to figure that out.
debug... unless you are a developer you can't.

Please follow the instructions in the "support" docs. Otherwise I really can't help. https://trapexit.github.io/mergerfs/latest/support/

Thanks for your repy. I'm using rsync to copy files on to the mounted volume. It's been running well for two days, ,and something just pops up and the mounted point was gone, I rebooted the machine to be able to mount it again. Now I guess I have to wait if the issue happens another time.
