@ty900000 The problem with using 114, is it’s missing an argument. So the Segfault is double’d due to -c/-a0 and not likely due to either of the arguments, but rather the fact partclone is segfaulting as it cannot determine file size, as it is literally commented out of the code. This means, a raw (imager) image file will not be generated at all. (/images/<imagename>/d1p<#ofparttion_to_be_cloned_in_imager_format>.img will be missing comletely.)
In my case the partition number was 2, and in yours it appears the partition number is 3.
I have created a fork of the partclone repository and implemented what I would think should address the issue by reimplementing the filesize display capabilities. As @Sebastian-Roth learned, simply uncommenting the line allowed partclone to work properly (as far as we could tell).
Until we patch the issue on our side (either by using our forked copy of the repository or directly implementing it as a part of the build process), this is still going to be a problem. I think we have a way to fix it, just haven’t had time to implement and have you (or anybody else who’d be willing) to test it.
