Description
Server crashes in Item_ref::fix_fields/Item::fix_fields_if_needed, assertion `*ref && (*ref)->fixed()' failed in Item_ref::fix_fields
We found a memory corruption bug that crash the debug build of mariadb.
POC:
—
CREATE TABLE v0 ( v1 INT ) ; |
INSERT INTO v0 ( v1 ) VALUES ( 60 ) ; |
UPDATE v0 SET v1 = NULL BETWEEN ( SELECT 95 FROM v0 WHERE v1 = 95 AND v1 < -1 GROUP BY - 'x' >= v1 HAVING ( -128 = 2147483647 AND v1 = 94 ) ) AND 36 WHERE v1 = 2 ; |

Stack dump:

200505 5:53:28 [ERROR] mysqld got signal 11 ;

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.
|
|
To report this bug, see https://mariadb.com/kb/en/reporting-bugs
|
|
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.

Server version: 10.5.3-MariaDB-debug
|
key_buffer_size=134217728
|
read_buffer_size=131072
|
max_used_connections=3
|
max_threads=153
|
thread_count=4
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 467925 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...
