Binary fails with segmentation fault

[apapsch]

I downloaded your binary 0.5.10, checksum matches. It crashes on Fedora 32 Workstation. Building from source seems to be alright (I got the help displayed).

$ ./img-linux-amd64 -h

I see the exact same error in Ubuntu 20.04 in WSL2.

Yup. Same error on my end as well 😟

Tried running 0.5.10 with Ubuntu 20.04 x86_64

Fails in Ubuntu 18.04.5 LTS
