strace of the segfaulting process
Description of problem:
sshd crashes before asking for password. Looks to be working with -8/-7 or older.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. ssh localhost
2. accept unknown key warning
no password prompt,
sshd: segfault at 58258880 ip 00007feb565a8c58 sp 00007fff81415520 error 4 in libaudit.so.1.0.0[7feb565a2000+16000]
I was unable to grab a backtrace, attaching to sshd and setting "set follow-fork-mode child" won't stop on segfault and I only get "Program exited with code 0377."
No abrt here (various reasons), debugging hints welcome, already reported the gdb issue to jkratochvil.
So attaching a strace report instead.
Me too. Message on server console when trying to ssh from clinet.
sshd: segfault at ffffffff830b7830 ip 00007f9881a8dc58 sp 00007fffd3faddd0 error 4 in libaudit.so.1.0.0[7f9881a87000+16000]
Problem goes away with downgrade to: openssh-5.6p1-8.fc15.x86_64.rpm
Doesn't seem to happen on i686.
