--- Comment #20 from Mark Wielaard <mark at klomp dot org> --- (In reply to Michael Hudson-Doyle from comment #19) > I see a similar looking failure on arm64 on Ubuntu 18.10: > > https://launchpadlibrarian.net/391377304/buildlog_ubuntu-cosmic-arm64. > elfutils_0.170-0.5_BUILDING.txt.gz So, if possible could you build with current git or 0.174 + the patch from comment #14 or commit 69d6e67eee30c483ba53a8e1da1b3568033e3ddecommit 69d6e67eee30c483ba53a8e1da1b3568033e3dde > I've gdb-ed this to the point that the key difference between a working > system (Ubuntu 18.04) and the failing one is that libc.so.6 has a lot more > entries in .eh_frame_hdr in the failing system. On 18.04 it fails to find a > fde for abort() (or raise, I think) and unwinds using .debug_frame and that > succeeds.

I don't know either why the newer > libc.so.6 has a bigger eh_frame_hdr (it is glibc 2.28 vs 2.27 but also built > with newer gcc and binutils) or why unwinding using eh_frame info fails. In principle the .eh_frame and .debug_frame should provide the same CFI, although encoded slightly differently. Maybe there is a difference? You should be able to find both with eu-readelf --debug-dump=frame -- You are receiving this mail because: You are on the CC list for the bug.
