In a clang/libcxx/llvm profile, software might print out debug messages related to libunwind on the command line, such as in the following example: --- ~% mpv empty.wav libunwind: __unw_add_dynamic_fde: bad fde: FDE is really a CIE libunwind: __unw_add_dynamic_fde: bad fde: FDE is really a CIE [ffmpeg/demuxer] wav: Cannot check for SPDIF (+) Audio --aid=1 (pcm_s16le 2ch 44100Hz) Exiting... (Errors when loading file) --- Adding "-DNDEBUG" to CPPFLAGS during the emerge of sys-libs/llvm-libunwind prevents this from happening, so I suggest updating the ebuild accordingly. ~% emerge --info

I can confirm that this is required, upstream has also confirmed https://github.com/llvm/llvm-project/issues/86#issuecomment-1649668826
Sorry, I meant to look at this one when handling the clang-common bits.
