+defaults to @code{on}.
+
+To call a function in the program, @value{GDBN} has to temporarily
+modify the state of the inferior.  This has potentially undesired side
+effects.  Also, having @value{GDBN} call nested functions is likely to
+be erroneous and may even crash the program being debugged.  You can
+avoid such hazards by forbidding @value{GDBN} from calling functions
+in the program being debugged.  If calling functions in the program
+is forbidden, GDB will throw an error when a command (such as printing
+an expression) starts a function call in the program.
