C and C++ type and range checks
By default, when GDB parses C or C++ expressions, type checking is not
used. However, if you turn type checking on, GDB considers two
variables type equivalent if:
* The two variables are structured and have the same structure,
union, or enumerated tag.
* The two variables have the same type name, or types that have been
declared equivalent through `typedef'.
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.
