hi! after a recent update of the portage tree and installing some updated packages i ran "revdep-rebuild". this segfaults with this message in /var/log/messages: Mar 16 18:04:14 area52

revdep-rebuild is a bash script; that's definitely not what segfaults.
(In reply to comment #1) > revdep-rebuild is a bash script; that's definitely not what segfaults. > i know that it is a script. but it happens while executing it so i thought to open a bugreport...
it all depends on what is making it crash run: bash -x revdep-rebuild <whatever args you normally use> >& bash-x.log strace -f -o strace.log -s 4096 revdep-rebuild <whatever args you normally use> and then post those two log files as an attachment

none of the vdso's should be loaded directly by the ldso, so i dont think it's worthwhile to track down why ldso crashes when doing ldd on it revdep-rebuild should just filter out vdso/linux-gate hits

it means you can safely ignore the segfaults
(In reply to comment #9) > it means you can safely ignore the segfaults > i recognized in the strace output that modules of kernel 2.6.24 are used: 13557 execve("/lib/ld-linux.so.2", ["/lib/ld-linux.so.2"..., "--verify"..., "/lib64/modules/2.6.24-gentoo-r3/vdso/vdso32-sysenter.so"...], [/* 22 vars */]) = 0 is it possible that the error occurs cause i only have compiled the new 2.6.24-gentoo-r3 kernel but did not boot it? currently i have 2.6.23-gentoo-r9 booted.

Changing the 99revdep-rebuild file works, however, that file gets overwritten with every installation of gentoolkit. For this case, that probably doesn't matter. From the revdep-rebuild manpage: "environment settings - one time changes by user /etc/make.conf - persistent changes by user /etc/revdep-rebuild/* - persistent changes by ebuild authors While a user can edit and modify the files in the /etc/revdep-rebuild directory, please be aware that the /etc/revdep-rebuild directory is not under configuration protection and files can be removed and/or overwritten by an ebuild. To change this add /etc/revdep-rebuild to the CONFIG_PROTECT variable in /etc/make.conf." I've fixed the 99revdep-rebuild file in subversion to exclude /lib*/modules.
