Ping? Any progress on merging this functionality upstream? It can make quite a difference in unwinding. I just got a report from a colleague. As-is, elfutils would fail to unwind from the following location in his application: 0x1137ca4 With the x86_64 patch applied, he got a proper backtrace: 0x1137ca4 0xc45466 0xc4fffa 0xda76f3 0xd78181 0xd8069c 0xd846bd 0xd995b7 QOpenGLFunctions::glTexImage2D qopenglfunctions.h:1022 ... <proper debug symbols available rom here on> So, please consider reviewing and merging this.
