I have this lines:

```
char* data = (char *) mmap(NULL, size, PROT_READ, MAP_SHARED, fd, offset);
...
size_t lineLength = strlen(data);
char *out = calloc(lineLength, sizeof(data));

```

at the last line I get with the new XCode the following warning

```
Result of 'calloc' is converted to a pointer of type 'char', which is incompatible with sizeof operand type 'char *'

```

I stuck a bit is this a real complain?
