ah ok, thanks.

While I have your attention, I sometimes (well pretty often actually) got this
inside my gdb session:

   (gdb) n
   warning: Invalid remote reply: 00

or

   (gdb) n
   warning: Invalid remote reply: 00
   warning: Invalid remote reply:
c0dcb40f0081ffff08e59f0f0081ffff00b1a40f0081ffff8086400f0081ffff704e2c81ffffffff01000000008000000d00000000000000000000000000000000000001000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000002000000000000000ffffffffffffffff0000000000000000

Do you any idea what's wrong in this case ?

thing.
