Zusammenfassung:The disclosure provides a method for detection of an uninitialized variable. The method includes running a first function, wherein the first function comprises a local variable and a first flag associated with the local variable for indicating an initialization state of the local variable; calling a second function from the first function, with the local variable as a parameter of the second function, wherein the second function comprises a second flag associated with the parameter for indicating an initialization state of the parameter; and updating the first flag based at least on the second flag returned from the second function.
