^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Thus the important patch is in place, skas mode is enabled, thus it IS
SKAS MODE.

That means I was right and debug is not apropriate in your situation.
You need to simply start this all from gdb. You want to use gdb's tty
commad because gdb wouldn't see interrputs otherwise. You also want to
set handling of SIGUSR1, SIGTRAP and SIGSEGV to nostop noprint pass.

(I have some controling scripts to do the work. I think I have already
posted them, but I might post them again if someone is interested).
