the machine has to be rebooted.

it is a program that a colleague in Brisbane wrote. He has crashed the
machine several times this afternoon running it. However I just ran
the short program he sent me without any problems (other than a seg
fault) -- in other words I dont think we have tracked down where the
problem is.
I will get the full program and run it with gdb, then perhaps I can give you
further information
