+// 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.
