Memory Access Violation

Memory access violation summarized as follows:

Memory access violation occurs when the following conditions are met accessed in two:

a. at least one write operation

b. they access the same piece of memory

c. They overlap an access time (for example, in the same function)

 

Example 1:

. 2-3-4 Example:

 

The focus is error to find the problem not to tangle! ! !

If the following condition is satisfied , it means access to the overlapping property of the structure is safe :

/*

 1. Only access memory attributes instance, instead of computing the attribute or attribute class (as in the global area equivalent)

 2. The structure of a local variable is not the global variable

 3. The structure is either not or only the closure by a non-captured escape capture closure

 */

Example a: (tuple structure) as a local variable in a function which is the
