--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
GCC also does not delete allocated memory when used in loop:
```
void foo(int n)
{
   {
     int *a = __builtin_malloc(n*sizeof(int));
     for (int i=0;i<n;i++) a[i] = i;
     __builtin_free(a);
   }
   printf(" ");
}
```

Let me find the dup.
