a Seg. Fault happens due to programmer error, they told the
program to write memory outside of where it should have. A
seg fault should not normally happen due to an out-of-memory

when a program eats up all the system memory, the OS is left
which a choice of what to do, as it needs memory too, and the
choice it makes is to protect itself and kill the process which
is eating up all the memory. I'm not sure what the translation
would look like, for me I think it's like "Process killed."

try watching the process in `top` in a Terminal window to
see how much memory it uses, and keep going and try changing
the region res= to be as coarse as 5m.
