Title:
  crash on STRAIGHT_JOIN query - lt-drizzled:
  drizzled/diagnostics_area.cc:119: void
  drizzled::Diagnostics_area::set_eof_status(drizzled::Session*):
  Assertion `! is_set()' failed.

Status in A Lightweight SQL Database for Cloud Infrastructure and Web Applications:
  Confirmed

Bug description:
  This randgen-generated monstrosity:
  (will work on simplification as time permits)

  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'

  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.
