Scott, that's a positive on RH 7.2, 7.0, and LinuxPPC Q4 dist. Good find. core dump: #0 0x400748cf in _IO_vfprintf (s=0xbfffd3c0, format=0x8049928 "%s: %s", ap=0xbfffd5ac) at ../sysdeps/i386/bits/string.h:343 #1 0x4008ea68 in _IO_vsprintf ( string=0xbfffd490 "/dev/", 'A' <repeats 195 times>..., format=0x8049928 "%s: %s", args=0xbfffd5a4) at iovsprintf.c:49 #2 0x08048f96 in alarm () #3 0x41414141 in ??

*nix Issue - Anyone with 'mingetty': After all the vi overflows, and wu-ftpd etc recently I thought I would have a sniff around a default redhat 7.1 box too see what I could find. Anyway I managed to dump core on /sbin/mingetty and thought it would be worth reporting: See below for the shell out: [m0le@mainframe m0le]$ /sbin/mingetty `perl -e 'print "A"x9000'` Segmentation fault (core dumped) [m0le@mainframe m0le]$ id uid=500(m0le) gid=500(m0le) groups=500(m0le) (standard user account) This only works by doing this: /sbin/mingetty `perl -e 'print "A"x9000'` when I did the following: [m0le@mainframe m0le]$ cd /sbin [m0le@mainframe /sbin]$ ./mingetty `perl -e 'print "A"x9000'` Segmentation fault [m0le@mainframe /sbin]$ No core dump.... It doesn't seem to dump in the sbin directory, however I've successfully dumped from several other dir's. I am running a RedHat7.1. I would appreciate some feedback from other distros whith mingetty running. Thanks Scott Mackenzie.
