Log in as root and run the prelink job for the day.

/etc/cron.daily/prelink

Then retry both.

I found that 'su' started working again, but 'sudo' continued to segfault.

Comment 2 Steven Usdansky 2006-10-28 18:06:07 UTC

Rob Andrew's suggestion didn't work for me - neither su nor wsudo worked.
Reverting to glibc-2.5-3 did the trick for me.

Comment 4 Jakub Jelinek 2006-10-29 08:26:35 UTC

Any suid/sgid app is broken actually, as a result of
http://sources.redhat.com/ml/libc-hacker/2006-10/msg00017.html
ld.so calls __libc_fcntl that uses SINGLE_THREAD_P before %fs resp. %gs is set
up.

noting the same problem and adding to the CC.
Questioning comment #5. Is this patch going to lead to a newer package release?

Comment 7 Paul Dickson 2006-10-30 03:13:42 UTC

dovecot is also getting "killed with signal 11" when I attempt a TLS download of
E-mail.  Reverting back to glibc-2.5-3 allowed dovecot to function.

Comment 8 Jakub Jelinek 2006-10-30 10:16:34 UTC

Should be fixed in glibc-2.5.90-3 in today's rawhide.
