Created attachment 795 [details] repro of cursor delete bug

Thanks for the report. Broken by the patch for ITS#9376. Fixed now in git.

See attached source code for reproduction. The test behaves correctly in 0.9.26 and fails in 0.9.27 and 0.9.28.

The failing sequence is:

1. In a dupsort DB, create two different keys and values.
2. Create a cursor, setting the position to the second key.
3. Delete the first key.
4. Have the cursor get the next key. mdb_get_key will return the second key

instead of returning MDB_NOT_FOUND.
