Range checking, if turned on, is done on mathematical operations. Array indices are
not checked, since they are often used to index a pointer that is not itself an array.

9.4.1.6 GDB and C

The set print union and show print union commands apply to the union
type. When set to 'on', any union that is inside a struct or class is also printed.
Otherwise, it appears as '{...}'.

The @ operator aids in the debugging of dynamic arrays, formed with pointers and a
memory allocation function. See

“Expressions” (page 83)
