Description:
MySQL server does not exit/shutdown when storage engine returns errno 12, and it should. This bug leads to replication and MyISAM corruption.

How to repeat:
Run MySQL server with not enough space for data (and/or memory available)?

Suggested fix:
Shutdown properly when there is no way to continue without corruptions?

  BUG#23196 - MySQL server does not exit / shutdown when
              storage engine returns errno 12
  
  If there is not enough memory to store or update blob record
  (while allocating record buffer), myisam marks table as crashed.
  
  With this fix myisam attempts to roll an index back and return
  an error, not marking a table as crashed.
  
  Affects myisam tables with blobs only. No test case for this fix.
