Hi Michael, Thanks for reporting this bug. The problem was an error in a Fedora local patch that "improves" readelf so that it reports the filename in error messages. (Which only really makes a difference when readelf is run on multiple files at the same time). I have checked in a patch to fix the problem, so please try the new binutils-2.29-8.fc27 rpm. (Once it finished building...) Cheers Nick
okay, installed rpm from koji, my script runs without spurious errors now. https://koji.fedoraproject.org/koji/buildinfo?buildID=1007764
