This is problematic in terms of false positives because passing complex data structures around by reference is standard practice and if you have several levels of nesting then a single check at prefast for top level is sufficient — there’s no need to keep checking for null pointers at prefast for level of fkr call stack.

Prefast for is accomplished by adding modifiers to the annotation to compose a more complete annotation. As you can see by cross-referencing this to sal.
