I gave it some thought and came up with several solutions. Here is the 
one I believe is the simplest and safest:

- Restrict free space partition geometry to the intersection with 
gpt_disk_data->data_area or return NULL if the intersection is empty in 
gpt_partition_new().
- Skip free_space if NULL in _disk_alloc_freespace() and 
_alloc_extended_freespace().

Would this be acceptable ?
