New checks (inconclusive): Suspicious calculation with sizeof()
...
- Check for sizeof(ptr)/something: This indicates that programmer was trying to calculate array size, but sizeof(ptr) doesn't return the length of the memory area, but size of a pointer.
- Check for sizeof()*sizeof(): This indicates that programmer misunderstood what sizeof() does: It does return the length in bytes of the given variable, not e.g. the number of elements in an array.
