Cast the fifth arg to mremap to void *
Summary:
Since the prototype of mremap is
```
void *mremap(void *old_address, size_t old_size, size_t new_size,
int flags, ... /* void *new_address*/);
```
we need to cast new_address to void * when calling mremap. Otherwise,
the wrong value will be passed to mremap on x32.
