Description rouzier@gmail.com 2015-04-19 16:28:09 UTC 
Full_Name: James Rouzier
Version: LMDB mdb.master
OS: linux
URL: https://gist.github.com/rouzier/2d268a2f24e82e00f498
Submission from: (NULL) (70.81.32.80)


When iterating with a cursor using MDB_PREV and deleting entries using
mdb_cursor_del.
It will crash when calling mdb_cursor_get after the last entry was deleted.
I am using the latest version of LMDB in git.
