This randgen-generated monstrosity:

SELECT STRAIGHT_JOIN table2 . `col_bigint_not_null_key` AS field1 , table2 . `pk` AS field2 , table1 . `col_enum_key` AS field3 , table1 . `pk` AS field4 FROM ( C AS table1 INNER JOIN ( ( DD AS table2 STRAIGHT_JOIN BB AS table3 ON (table3 . `col_char_1024_key` = table2 . `col_char_10_not_null_key` ) ) ) ON (table3 . `col_char_1024_not_null` = table2 . `col_char_10_key` ) ) WHERE ( ( table1 . `col_int_not_null` , table3 . `col_bigint_key` ) IN ( SELECT SUBQUERY1_t1 . `col_int_not_null` AS SUBQUERY1_field1 , SUM( SUBQUERY1_t1 . `col_int_not_null_key` ) AS SUBQUERY1_field2 FROM ( AA AS SUBQUERY1_t1 INNER JOIN AA AS SUBQUERY1_t2 ON (SUBQUERY1_t2 . `col_int_not_null_key` = SUBQUERY1_t1 . `col_int_not_null` ) ) WHERE ( SUBQUERY1_t1 . `col_char_1024` >= SUBQUERY1_t1 . `col_char_1024_key` AND SUBQUERY1_t2 . `col_bigint` = 8 ) ) ) AND table3 . `col_char_1024_not_null_key` <= 'r'

is causing this crash output:

This could be because you hit a bug. It is also possible that this binary
 or one of the libraries it was linked against is corrupt, improperly built,
 or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help diagnose
the problem, but since we have already crashed, something is definitely wrong
and this may fail.

read_buffer_size=131072
max_used_connections=3
connection_count=2
It is possible that drizzled could use up to
(read_buffer_size + sort_buffer_size)*thread_count
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

To repeat:
from the attached branch, execute the following:
./kewpie.py --suite=randgen_basic optimizerSubquery_test
or make test-randgen ; )

The test will dump the error log as part of it's failure. randgen output can be found in kewpie/workdir/bot0/log/randgen.out
