Package: libc6 Version: 2.3.2-9
The shell command 'sleep 1' gives an 'illegal instruction' error. As you can see below, apparently on an stmxcsr. (I don't speak assembler very well :-) This is with the current 'testing' glibc. Very likely a libc problem. Apparently someone's encountered that already, but I didn't find it filed as a bug: http://lists.debian.org/debian-user/2003/debian-user-200310/msg02806.html I don't know for sure whether it's a problem of libc, kernel, or the sleep program, but I can give two configurations with different behaviour: Config 1 (works): ***************** $ uname -a Linux lrnoe 2.4.18-1-386 #2 Sun Aug 10 09:10:41 EST 2003 i686 unknown $ dpkg --list kernel-image-2.4.18-1-386 ii kernel-image-2 2.4.18-11 ... $ dpkg --list libc6 ii libc6 2.3.2-7 ... $ /lib/libc.so.6 GNU C Library stable release version 2.3.2, by Roland McGrath et al. ...
