Just 20 minutes age when I answered a question, I come up with an interesting scenario that I'm not sure of the behavior:

Let me have an integer array of size n, pointed by intPtr;

int* intPtr;

and let me also have a struct like this:

typedef struct {
int val1;
int val2;
//and less or more integer declarations goes on like this(not any other type)
}intStruct;

My question is if I do a cast intStruct* structPtr = (intStruct*) intPtr;

Am I sure to get every element correctly if I traverse the elements of the struct? Is there any possibility of miss-alignment(possible because of padding) in any architecture/compiler?
