unknown 863b86db24 Fix for bug #33758: Got query result when using ORDER BY ASC, but 
empty result when using DESC

Problem: fetching MyISAM keys we copy a key block pointer to the end of the key buffer.
However, we don't take into account the pointer length calculatig the buffer size,
that may leads to memory overwriting and in turn to unpredictable results.

Fix: increase key buffer size by length of the key block pointer.

Note: no simple test case.


myisam/mi_open.c:
  Fix for bug #33758: Got query result when using ORDER BY ASC, but 
  empty result when using DESC
    - increase possible maximum key length by size of the key block pointer,
      as it's copied into the key buffer in the get_key() MyISAM functions.
