Bug #14036214 MYSQLD CRASHES WHEN EXECUTING UPDATE IN TRX WITH

Browse Source 
CONSISTENT SNAPSHOT OPTION

A transaction is started with a consistent snapshot.  After 
the transaction is started new indexes are added to the 
table.  Now when we issue an update statement, the optimizer
chooses an index.  When the index scan is being initialized
via ha_innobase::change_active_index(), InnoDB reports 
the error code HA_ERR_TABLE_DEF_CHANGED, with message 
stating that "insufficient history for index".

This error message is propagated up to the SQL layer.  But
the my_error() api is never called.  The statement level
diagnostics area is not updated with the correct error 
status (it remains in Diagnostics_area::DA_EMPTY).  

Hence the following check in the Protocol::end_statement()
fails.

 516   case Diagnostics_area::DA_EMPTY:
 517   default:
 518     DBUG_ASSERT(0);
 519     error= send_ok(thd->server_status, 0, 0, 0, NULL);
 520     break;

The fix is to backport the fix of bugs 14365043, 11761652 
and 11746399. 

14365043 PROTOCOL::END_STATEMENT(): ASSERTION `0' FAILED
11761652 HA_RND_INIT() RESULT CODE NOT CHECKED
11746399 RETURN VALUES OF HA_INDEX_INIT() AND INDEX_INIT() IGNORED
