Initializes stack local variables to an unusual value to aid error detection.
- The compiler does not initialize local variables.
This option initializes stack local variables to an unusual value to aid error detection. Normally, these local variables should be initialized in the application. It also unmasks the floating-point invalid exception.
The option sets any uninitialized local variables that are allocated on the stack to a value that is typically interpreted as a very large integer or an invalid address. References to these variables are then likely to cause run-time errors that can help you detect coding errors.
This option sets option
/Z7(Windows*), which changes the default optimization level from
/Od(Windows). You can override this effect by explicitly specifying an
/Qtrapuv(Windows) are used together, you should specify option
/Qfp-speculation:safe(Windows) to prevent exceptions resulting from speculated floating-point operations from being trapped.
