Hi! Thank you for response! Sorry, I can’t come up with a good example of using
dangling pointers from real-world code, only exotic ones. I was just puzzled by
the fact that such an example with dangling pointer using doesn’t trigger a
warning from the checker, while, for example, the one from the topic raise "use
after free":
```c
#include "stdio.h"
#include "stdlib.h"
void test() {
int *p = (int*)malloc(sizeof(int));
free(p);
if (p) { // no warning
printf("smth");
}
```
