Description

This option determines whether checking occurs for uninitialized variables. Option -check-uninit enables this checking.

If a variable is read before it is written, a run-time error routine will be called.

Run-time checking of undefined variables is only implemented on local, scalar variables. It is not implemented on dynamically allocated variables, extern variables or static variables. It is not implemented on structs, classes, unions or arrays.
