There seems to be a bug somewhere that causes a segfault upon shutting down the rigol-ds driver (tested with DS1052E). Happens with both sigrok-cli and PulseView. Happens on Linux and Windows. The driver works fine otherwise, just the shutdown has the problem.

I haven't checked whether this is a more generic issue with all scpi-based drivers or not.

sigrok-cli:

$ sigrok-cli --scan -l 5
[...]
