First, it's using NULL as an offset to a pointer structure

```
descriptor *create_descriptor( struct statement *stmt )
...
   init_object( &ret->hdr, SQL_HANDLE_DESC, &stmt->hdr );

Second a crash in set_desc_rec_win32, assumes that win32_funcs is valid.
SQLSetDescRec
...
struct descriptor *desc = (struct descriptor *)lock_object( DescriptorHandle, SQL_HANDLE_DESC );
-> set_desc_rec_win32(desc)
-> -> desc->hdr.win32_funcs->SQLSetDescRec
```
