https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=231790 --- Comment #6 from Ed Maste <emaste@freebsd.org> --- As far as I can tell readelf is broken before and after r338478 on BE mips64. It looks like it is indeed a false-positive invocation of the le conversion - a breakpoint on _libelf_mips64el_r_info_tom when running "objcopy --strip-debug geom_mirror.ko.works out" stops on: * thread #1, name = 'objcopy', stop reason = breakpoint 2.1 * frame #0: 0x000000528b50f5c4 libelf.so.2`_libelf_mips64el_r_info_tom(r_info=8589934621) at gelf_mips64el.c:74 frame #1: 0x000000528b50e9f2 libelf.so.2`gelf_getrela(ed=<unavailable>, ndx=<unavailable>, dst=0x00007fffffffe400) at gelf_rela.c:97 frame #2: 0x00000000002124b7 objcopy`copy_content [inlined] update_reloc(ecp=<unavailable>) at sections.c:832 frame #3: 0x00000000002123c1 objcopy`copy_content(ecp=<unavailable>) at sections.c:604 frame #4: 0x000000000020db67 objcopy`create_elf(ecp=0x0000000800877000) at main.c:389 frame #5: 0x000000000020f0a3 objcopy`create_file(ecp=0x0000000800877000, src="geom_mirror.ko.works", dst="geom_mirror.ko.works") at main.c:705 frame #6: 0x000000000020ec81 objcopy`main [inlined] elfcopy_main(ecp=<unavailable>, argc=<unavailable>, argv=<unavailable>) at main.c:1028 frame #7: 0x000000000020ec79 objcopy`main(argc=4, argv=0x00007fffffffe750) at main.c:1597 frame #8: 0x0000000000209095 objcopy`_start(ap=<unavailable>, cleanup=<unavailable>) at crt1.c:74 -- You are receiving this mail because: You are the assignee for the bug.help
