Any idea?

In dcrt0.cc
783       if (user_data->main)
(gdb) p __argc
$4 = 1
(gdb) p __argv
$5 = (char **) 0xaf1aa8
(gdb) s
784         exit (user_data->main (__argc, __argv, *user_data->envptr));
(gdb) p __argv
$6 = (char **) 0xaf1aa8
(gdb) p __argc
$7 = 1
(gdb) b main
Breakpoint 2 at 0x403270: file sshd.c, line 804.
(gdb) s
main (ac=0, av=0x0) at sshd.c:804
804     {
Current language:  auto; currently c

$8 = 0
(gdb) s
834             for (i = 0; i < ac; i++)
(gdb) p ac
$9 = 0
(gdb) s

Program received signal SIGILL, Illegal instruction.
