NoQ added inline comments.


================
Comment at: clang/test/Analysis/malloc-static-storage.cpp:33-38
+void malloc_escape() {
+  static int *p;
+  p = (int *)malloc(sizeof(int));
+  escape(p); // no-leak
+  p = 0; // no-leak
+}
----------------
The main problem with static locals is that this can happen the other way round:

```lang=c
void malloc_escape() {
  static int *p;
  escape(p);
  p = (int *)malloc(sizeof(int));
  p = 0; // no-leak
}
```
