segment /seg'ment/ vi.
To experience a segmentation fault. Confusingly,
this is often pronounced more like the noun `segment' than like
mainstream v. segment; this is because it is actually a noun
shorthand that has been verbed.
Node:segmentation fault,
Next:segv, Previous:segment, Up:= S =
segmentation fault n.
[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.
