I confirm that this one line is causing the trouble:

root@arrakis:~> ls -l /dev/null
crw-rw-rw-  1 root root 1, 3 2006-01-18 13:34 /dev/null
root@arrakis:~> echo "main() {}" | gcc -xc - -o /dev/null
root@arrakis:~> ls -l /dev/null
crwxrwxrwx  1 root root 1, 3 2006-01-18 13:34 /dev/null
root@arrakis:~> 

This is with both gcc 3.3.6 from Slackware 10.2 and gcc 4.0.2 from Suse
10.0. Didn't try with self-compiled gcc versions on these systems.

BTW, I have noticed recently an "a.out" file at the root of my linux
sources tree when I build a kernel.

-rwxr-xr-x   1 khali users  11K 2006-01-16 19:51 a.out*

Running it doesn't seem to do anything useful. Is this file generated
here on purpose? Is it somehow related to the current issue?

Thanks,
