SEGFAULTs can often mean you are running out of memory. 

Though the tov_ET parfile uses very little memory for me: 200MiB (but
does reserve quite a bit more memory as virtual memory, namely ~1GiB).

You may need to run "top" in a second bash window to see how much
memory your run is using (you can type "e" to change units to more
useful ones).

If you are actually running out of memory (which I kind of doubt, but
who knows) then you can try increasing memory for WSL2.

Since wsl2 is a (thin) virtual machine it is limited by how much memory
it can use.

Can you try if reserving more memory for the VM helps?



for how to do that.

I also noticed that the speed is a bit slower than expected with only
~71M/hr while my (old) workstation reaches ~1700M/hr.

For me the TOV
