Subject: libc6: "Inconsistency detected..." and segfaults on 2.6? Followup-For: Bug #210840 Package: libc6 Version: 2.3.2.ds1-10 Severity: important
I have found this "Inconsistency detected by ld.so" bug few times on 2.6 kernels using both dual-processor server machine and SiS-chipset based laptop. It doesn't seem to depend on nVidia openGL drivers as suggested by http://www.mail-archive.com/[email protected]/msg07657.html. (Or it is another bug.) On every system I had this problem, I also had unexpected segfaults of dynamically linked libraries (libdbd-pg-perl in postgresql_autodoc on laptop, libg2c0 on a server). Downgrading to Debian Stable was the only way I found to fix the problem. Here is the transcript summarizing my recent observations: bash-2.05b$ cp /lib/libc-2.3.2.so /tmp/ bash-2.05b$ chmod u+x /tmp/libc-2.3.2.so bash-2.05b$ /tmp/libc-2.3.2.so Inconsistency detected by ld.so: rtld.c: 1259: dl_main: Assertion `_rtld_local._dl_rtld_map.l_prev->l_next == _rtld_local._dl_rtld_map.l_next' failed! bash-2.05b$ uname -a Linux dalia 2.6.0 #3 Sun Dec 21 13:08:29 CET 2003 i686 GNU/Linux bash-2.05b$ /lib/ld-linux.so.2 --verify /lib/ld-linux.so.2 bash-2.05b$ /lib/ld-linux.so.2 /lib/ld-linux.so.2 Segmentation fault bash-2.05b$ cp /lib/ld-linux.so.2 /tmp bash-2.05b$ /lib/ld-linux.so.2 /tmp/ld-linux.so.2 Inconsistency detected by ld.so: ../sysdeps/i386/dl-machine.h: 647: elf_machine_rel_relative: Assertion `((reloc->r_info) & 0xff) == 8' failed!
