[Unix] 1. [techspeak] An error in
which a running program attempts to access memory not allocated to
it and core dumps 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.
aliasing bug: n. A class of subtle programming errors that can
arise in code that does dynamic allocation, esp. via
`malloc(3)' or equivalent. If several pointers address
(`aliases for') a given hunk of storage, it may happen that the
storage is freed or reallocated (and thus moved) through one alias
and then referenced through another, which may lead to subtle (and
possibly intermittent) lossage depending on the state and the
allocation history of the malloc {arena}....
