No I said it get's a "memory fault, signal 8".  Usually the program dumps
core.  (ie. Memory fault - core dumped).  I see core files laying around
all over.  The system hasn't crashed because of this, unless the NMI (parity
error) was in the kernel, then probably the system would panic and die.

The pointer stuff and this is unrelated, you were right about that.

My problem is either heat, bad memory chip, or a combonation of both.
