Summary0001412: Unable to build it, because of the default compiler flags on Fedora and unclean code
DescriptionFedora will set this flags by default:
-Werror=maybe-uninitialized
-Werror=format-truncation
But then it fails at:

The same will happens using the Fedora 34 compiler default settings,

Also for build on RHEL-8 and RHEL-7(using Red Hat Developer Toolset 11.0 , because the default compiler don't support cx17).

Yeah, but just if you build the ndmpjob binary, which we usually don't.
Nevertheless, I fixed it, but the PR ist not yet merged.

btw... the fix is going onto master only. If you need to build the ndmpjob binary (and I really doubt that you do), you can add the patch during packaging - should be straightforward.
