The issue shows a Dockerfile that builds pakkero from source and uses it to pack a simple C program. The packed binary does not output anything. Start by examining the pakkero source, especially the packing logic and the launcher for ELF binaries. Look at the Makefile and the main.go entry point. Reproduce the issue locally to see if the packed binary fails silently or crashes. Check the project's test suite for any existing tests about packing and running binaries.
