- The linker also adds -w / --no-warnings options to suppress the generation of any warnings or error messages if there is a need to create a known, non-working binary.

I'm struggling to think of a use case for this..? Unit tests of ELF parsers? You would probably want to have specific hand made examples committed in your git repo for that, rather than rely on being able to build the same broken ones in the future...

Testing/abusing things sounds about right.
I mean, it would be akin to a packet generator being able to create invalid injected packets for testing purposes?

Sure, but generally I imagine you would want even more control over the resulting binary in those cases. I would not want to rely on a tool which is normally meant to produce working binaries and which probably has not guaranteed that it will produce bit identical non-working binaries in future releases. But maybe combined with custom linker scripts (which I admit to knowing very little about beyond that they are a thing) that would work.

It just seems (to me) that for testing purposes you would want a tool purpose made for giving you full control over all details.

What's the story with Debian starting to use zstd in packages? That never happened it seems.

now that 2.40 is out the door, why is Fedora being so Lame an sticking with 2.39 for F38? even Ubuntu 23.04 will have it
