I think this qualifies as a newbie question

ahmm... 
what is 'Segmentation Fault' ?
..
I realize (think) that this is the same as a win user asking - 'what does
the blue screen with the title - Fatal Exception means ?' but I would
really like a detailed explanation, as that is just the message I got
after I tried to compile some big proggy, 10 secs before my comp gone
bonanzay.
