I don't remember any specific fixes for clang in libdw for elfutils 0.171. But elfutils 0.171 was the first release that supported most of DWARF5 (including GNU DebugFission and split dwarf). > If there's any interest, it'd be fairly easy to add a check for this > condition under the check_deps() function in the script. Please do add this check. elfutils 0.170 is almost 6 years old now, there have been many, many bug fixes since then (current release is 0.188 from Nov 2022). Thanks, Mark
