Description
executing query:
SELECT * FROM |
( SELECT 100 a, subsel.b FROM ( SELECT 200 b ) subsel ) tmp |
WHERE tmp.b; |
shows correct result:
a b
|
100 200
|
but server crashed after query:
SELECT * FROM |
( SELECT 100 a, subsel.b FROM ( SELECT 200 b ) subsel ) tmp |
WHERE tmp.a; |
server log:
Server version: 10.0.6-MariaDB
|
key_buffer_size=134217728
|
read_buffer_size=131072
|
max_used_connections=1
|
max_threads=153
|
thread_count=1
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 467125 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out

where mysqld died. If you see no messages after this, something went

terribly wrong...
