Hi, Recently, there have started to appear weird messages in the build output of development snapshot of Ruby [1]:
``` ... snip ... + /usr/lib/rpm/find-debuginfo.sh --strict-build-id -m --run-dwz --dwz-low-mem-die-limit 10000000 --dwz-max-die-limit 110000000 /builddir/build/BUILD/ruby-2.4.0-r56693 ... snip ... extracting debug info from /builddir/build/BUILDROOT/ruby-2.4.0-0.1.r56693.fc26.x86_64/usr/lib64/libruby.so.2.4.0 /usr/lib/rpm/debugedit: /builddir/build/BUILDROOT/ruby-2.4.0-0.1.r56693.fc26.x86_64/usr/lib64/libruby.so.2.4.0: DWARF version 0 unhandled extracting debug info from /builddir/build/BUILDROOT/ruby-2.4.0-0.1.r56693.fc26.x86_64/usr/bin/ruby-mri ... snip ... dwz: ./usr/lib64/libruby.so.2.4.0.debug: DWARF version 0 unhandled ... snip ... ``` This was apparently introduced by upstream commit [2], which adds "--compress-debug-sections=zlib" as one of linker options. What I actually don't understand what are the implications of this. * It seems that RPM cannot handle the compressed debug info properly, does it also mean that the debuginfo is not stripped? * Should I ask RPM guys to add support for this? * Should I remove this flag? Should I ask upstream to make the compression optional?
