strace is either broken again or debian didn't pick up your fix.  The link
to your updated version is broken.

This happens when tracing sshd during a connection attempt with -f option:

strace -f -p 2390
Process 2390 attached - interrupt to quit
_newselect(7, [3 4], NULL, NULL, NULL
...
[pid  5627] open("/etc/selinux/config", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
upeek: ptrace(PTRACE_PEEKUSER,5627,4294967292,0): Input/output error
Process 5627 detached
<... _newselect resumed> )              = 1 (in [6])

Trying to figure out why sshd sometimes does wierd stuff.

Dave
