I've played with your code for a while, it really crashed my computer
but NOT due to floating point. The trouble was my computer does not have
/dev/rtf6
After all fifo operations were re-directed to /dev/rtf0, your test start
to work. My guess is you have to do the same. If not, let me know to learn
something :-) Another possible cause of trouble (less probable) is that
I don't use SMP (one Pentium only in my box). The best way to avoid this
kind of trouble is always to check return value of RTL functions.
Have a nice day.
