In the following example, the address of structure member foo.b is being cast as a struct pointer and then assigned to p. With lint -Xalias_level=weak (or higher), this generates a warning.
struct foo p{ int a; int b; }; struct foo *f1; struct foo *f2; void main() { f2 = (struct foo *)&f1->b; /* cast of a scalar pointer to struct pointer error*/ } |
