n. [C programming] A variety of fandango on core produced by scribbling past
|
|
|
|
|
the end of an array (C implementations typically have no checks for this
|
|
|
|
|
error). This is relatively benign and easy to spot if the array is static;
|
|
|
|
|
if it is auto, the result may be to smash the stack often resulting in
|
|
|
|
|
heisenbug s of the most diabolical subtlety. The term overrun screw is used
|
|
|
|
|
esp. of scribbles beyond the end of arrays allocated with malloc (3) ; this
|
|
|
|
|
typically trashes the allocation header for the next block in the arena ,
|
|
|
|
|
producing massive lossage within malloc and often a core dump on the next
|
|
|
|
|
operation to use stdio (3) or malloc (3) itself. See spam , overrun ; see
|
|
|
|
|
also memory leak , memory smash , aliasing bug , precedence lossage ,
|
|
|
|
|
fandango on core , secondary damage.
