Package: debhelper,lintian Severity: wishlist dwz currently doesn't handle compressed debug sections. In the first place, why should we have these, because or dbg packages are compressed anyway. otoh, these are enabled by some upstreams like ruby.
So what dh_dwz could do, is - look for SHF_COMPRESSED - objcopy --decompress-debug-sections - dwz - objcopy --compress-debug-sections Or lintian could just warn about compressed debug sections.
