Variable character_set_results can legally be NULL (for "no conversion.")
This could result in a NULL deref that crashed the server.  Fixed.

(Although ran some additional precursory tests to see whether I could break
anything else, but no breakage so far.)

  Prove DATE_FORMAT() no longer crashes the server when character_set_results is
  NULL (which is a legal value and means, "no conversion").

  because it is magic for, "no conversion."

The problem is that the author used the wrong function to send a warning to the 
user about truncation of data.  push_warning() takes a constant string and 
push_warning_printf() takes a format and variable arguments to fill it.

Since the string we were complaining about contains percent characters, the 
printf() code interprets the "%Y" et c. that the user sends.  That's wrong, and
often causes a crash, especially if the date mentions seconds, "%s".

A alternate fix would be to use  push_warning_printf(..., "%s", warn_buff) .

closing temp tables through end_thread
had a flaw in binlog-off branch of close_temporary_tables where
next table to close was reset via table->next
 for (table= thd->temporary_tables; table; table= table->next)
which was wrong since the current table instance got destoyed at
	close_temporary(table, 1);

The fix adapts binlog-on branch method to engage the loop's internal 'next' variable which holds table->next prior table's destoying.



sql/sql_base.cc:
  no-binlog branch is fixed: scanning across temporary_tables must be careful to save next table since the current is being destroyed inside of close_temporary. 
  binlog-is-open case is ok.

dropping/creating tables".

The bug could lead to a crash when multi-delete statements were
prepared and used with temporary tables.

The bug was caused by lack of clean-up of multi-delete tables before
re-execution of a prepared statement. In a statement like
DELETE t1 FROM t1, t2 WHERE ... the first table list (t1) is
moved to lex->auxilliary_table_list and excluded from lex->query_tables
or select_lex->tables. Thus it was unaccessible to reinit_stmt_before_use
and not cleaned up before re-execution of a prepared statement.

  Updated test results (Bug#19399)
mysql-test/t/ps.test:
  A test case for Bug#19399 "Stored Procedures 'Lost Connection' when 
  dropping/creating tables": test that multi-delete
  tables are cleaned up properly before re-execution.
sql/sql_lex.cc:
  Always initialize auxilliary_table_list when we initialize the lex:
  this way we don't have to check that lex->sql_command equals to
  SQLCOM_DELETE_MULTI whenever we need to access auxilliary_table_list.
  In particular, in reinit_stmt_before_use we can simply check that
  auxilliary_table_list is not NULL and clean it up if the check returns
  a true value.
sql/sql_prepare.cc:
  Move the one table clean-up functionality to a method of st_table_list.
  Clean up auxiliary_table_list if it's not empty.
sql/table.cc:

On exactly-sized Strings, the String::c_ptr() function peeked beyond the
end of the buffer, possibly into unititialized space to see whether the 
buffer was NUL-terminated.

In a place that did peek improperly, we now use a c_ptr_safe() function, 
which doesn't peek where it shouldn't.
