// When an array of structures is created at a location, and the
|
|
// array type contains a pointer type, Ghidra will lay down valid
|
|
// references as long as the pointer is valid (points to something
|
|
// in memory). However, at the first sign of invalidity, the
|
|
// CodeManager bails and stops laying down references.
|
|
//
|
|
// This script, when run at the location of the array of structures,
|
|
// will update each individual structure element, iterating through
|
|
// the whole array until the end.
