Comment (by Kronuz):

 `ChertTable::open()` closes the table, which frees `C[j].p` and maybe
 (when it's lazy) `do_open_to_read()` doesn't create memory for those, yet
 returns true. Then later, when `ChertTable::find` is called, it uses
 `C_[j].p` but its memory doesn't exist as it has already been freed.

 Maybe `ChertTable::do_open_to_read` should always initialize the `C`
 cursor when returning true? (or even maybe always?)... also, the same
 might apply to `ChertTable::do_open_to_write` as well.
