Was trying to figure out how to run revdep-rebuild --library passing multiple libs to same command, I first tried: revdep-rebuild --library /usr/lib64/libicudata.so.48.1.1 /usr/lib64/libicuio.so.48.1.1 But it only runs for first lib (not sure if this is expected, but would be nice to allow that also). Later, I found this syntax: https://bugs.gentoo.org/show_bug.cgi?id=143498#c11 but, even if it should work, if segfaults: $ revdep-rebuild --library /usr/lib64/libicudata.so.48.1.1|/usr/lib64/libicuio.so.48.1.1 * You are not superuser. Adding --pretend to emerge options. Violación de segmento How can I get a backtrace from it?

revdep-rebuild is a bash script. So run bash -x revdep-rebuild and we should be able to see what executable is having the segmentation fault. The --library argument is passed to egrep, so to do multiple libraries, you need a valid extended regular expression. The syntax to do what you are trying to do is: revdep-rebuild.sh --library '/usr/lib64/libicu(data|io).so.48'

It looks like the segmentation fault is coming from 'einfo'. You can verify this by doing the following: source /etc/init.d/functions.sh einfo "Test" On my system /etc/init.d/functions.sh is owned by sys-apps/openrc

I'm stumped on how to further troubleshoot this. Based off of the bash -x output it is einfo that is having the segmentation fault. It works fine on my system and you're the only person to report this kind of error.
I see the following in dmesg when running it: libicuio.so.49.[8849]: segfault at 1 ip 0000000000000001 sp 00007fff545677a8 error 14 in libicuio.so.49.1.1[32f1800000+b000]
