in gdb, you should set the syspath before command continue.
It looks like that you are using the Sourcery G++ Lite cross tool-chain?
In its manual of gdb, a section "Setting the Sysroot in the Debugger" should be read.
Code:
(gdb) set sysroot-on-target target-pathname
(gdb) set sysroot host-pathnam
Then, ?? () may be disappeared.
Hope it be helpful.

I configured ddd to connect to the gdbserver on the beagleboard:
Code:
(gdb) target remote 192.168.0.1:2345
0x400007f0 in _dl_start_user () from /sourcery_root/lib/ld-linux.so.3
(gdb) target remote 192.168.0.1:2345
192.168.0.1:2345: Connection timed out.
(gdb) target remote 192.168.0.1:2345
0x400007f0 in _dl_start_user () from /sourcery_root/lib/ld-linux.so.3
(gdb) c
Program received signal SIGILL, Illegal instruction.
0x40045524 in ?? ()
(gdb) bt
#0 0x40045524 in ?? ()
#1 0x40025050 in ?? ()
Backtrace stopped: previous frame identical to this frame (corrupt stack?)
(gdb)
Could someone give a hint where to look at?
