Dell 1550, FBSD 4.5-Stable
>Description:
Telnet crashes when you type CTRL \ at the telnet> prompt.
GDB shows the following:
main (argc=1, argv=0xbfbffc44) at main.c:361
361 for (;;) {
(gdb)
367 command(1, 0, 0);
(gdb)
Program received signal SIGQUIT, Quit.
0x28136bfc in read () from /usr/lib/libc.so.4
(gdb)
>How-To-Repeat:
telnet
press CTRL \
>Fix:
Not sure best way of handling this, I assume just trapping sigquit and making it run a null function would work, but I
don't know if that's the best way.
