"Killed" as output on custom input

[yatharthahuja]

Hello!

The repo installed and compiled just fine but when I tried to pass on a custom input, I am getting the following output:

pi@raspberrypi:~/ELSDc $ ./elsdc input.pgm
Killed

I am working on RPi 3b+ Bulleseye OS. The same image as jpg input gave results on online demo; and the repo is working fine offline on the provided shape.pgm input. Any idea what's the issue?

Thanks in advance!
