objdump --line-numbers --disassemble --demangle --reloc --no-show-raw-insn --section=.text {}wich starts with objdump instead of readelf.
I don't know where to start with debugging this, maybe it's a version compatibility issue. Both programs are installed in the build/test environment, version 2.36.0.20210204-1 each.
