It was a test case problem: one 'reap' statement was forgotten.

Original commentary:

Bug #37348: Crash in or immediately after JOIN::make_sum_func_list
            
The optimizer pulls up aggregate functions which should be aggregated in
an outer select. At some point it may substitute such a function for a field
in the temporary table. The setup_copy_fields function doesn't take this
into account and may overrun the copy_field buffer.
            
Fixed by filtering out the fields referenced through the specialized
reference for aggregates (Item_aggregate_ref).
Added an assertion to make sure bugs that cause similar discrepancy 
don't go undetected.

The problem is that XML functions(items) do not reset null_value
before their execution and further item excution may use
null_value value of the previous result.
The fix is to reset null_value.

Problem: we don't prune a LESS THAN partition if MAXVALUE is given and
given value is equal to a LESS THAN value.

Fix: prune partitions in such cases.

The server crashes on an assert in net_end_statement indicating that the
Diagnostics area wasn't set properly during execution.
This happened on a multi table DELETE operation using the IGNORE keyword.
The keyword is suppose to allow for execution to continue on a best effort
despite some non-fatal errors. Instead execution stopped and no client
response was sent which would have led to a protocol error if it hadn't been
for the assert.
This patch corrects this issue by checking for the existence of an IGNORE
option before setting an error state during row-by-row delete iteration.

Test was flakey on some machines and showed spurious
reds for races.

New-and-improved test makes do with fewer statements,
no mysqltest-variables, and no backticks. Should hope-
fully be more robust. Heck, it's debatable whether we
should have a test for this, anyway.

updates

Attempt to execute trigger or stored function with multi-UPDATE
which used - but didn't update - a table that was also used by
the calling statement led to an error. Read-only reference to
tables used in the calling statement should be allowed.
 
This problem was caused by the fact that check for conflicting
use of tables in SP/triggers was performed in open_tables(),
and in case of multi-UPDATE we didn't know exact lock type at
this stage.

We solve the problem by moving this check to lock_tables(), so
it can be performed after exact lock types for tables used by
multi-UPDATE are determined.
