Reported when an address pointing into the stack of the current
|
||
|
|
function will escape to its calling context. Such addresses will
|
||
|
|
become invalid by the time the function actually returns so are
|
||
|
|
potentially dangerous.
|
||
|
|
|
||
|
|
For example, directly returning a pointer to a local variable:
|
||
|
|
|
||
|
|
```C
|
||
|
|
int* foo() {
|
||
|
|
int x = 42;
|
||
|
|
return &x; // <-- warn here that "&x" will escape
|
||
|
|
}
|
||
|
|
```
