Replicated on an updated Fedora 35, run-readelf-compressed-zstd.sh passes without valgrind, but fails running under valgrind. Specifically: $ cp tests/hello_i386.ko.bz2 . $ bunzip2 hello_i386.ko.bz2 $ zstd hello_i386.ko $ LD_LIBRARY_PATH=libelf:libdw src/readelf -a hello_i386.ko.zst > /dev/null $ LD_LIBRARY_PATH=libelf:libdw valgrind -q src/readelf -a hello_i386.ko.zst src/readelf: failed reading 'hello_i386.ko.zst': zstd decompression failed I haven't figured out why yet. Cheers, Mark
