[Unix]
1. [techspeak] An error in which a running program attempts to access
memory not allocated to it and {core dump}s with a segmentation
violation error. This is often caused by improper usage of pointers
in the source code, dereferencing a null pointer, or (in C)
inadvertently using a non-pointer variable as a pointer. The classic
example is:
int i;
scanf ("%d", i); /* should have used &i */
2. To lose a train of thought or a line of reasoning. Also uttered as
an exclamation at the point of befuddlement.
