    Details

      Description

      The following Query (Nextcloud) causes a Maria DB Failing assertion: dict_tf2_is_valid(flags, flags2):

      ALTER TABLE oc_talk_rooms ADD sip_enabled SMALLINT UNSIGNED DEFAULT 0 NOT NULL, ADD description LONGTEXT DEFAULT NULL, ADD listable SMALLINT UNSIGNED DEFAULT 0, ADD call_flag INT DEFAULT 0 NOT NULL
      

      The following stack trace is printed within the error logs:

      Error Log

      2021-09-09 12:22:54 0x7fc56cbea700 InnoDB: Assertion failure in file /home/buildbot/buildbot/build/mariadb-10.4.20/storage/innobase/dict/dict0mem.cc line 152
      InnoDB: Failing assertion: dict_tf2_is_valid(flags, flags2)
      InnoDB: We intentionally generate a memory trap.
      InnoDB: Submit a detailed bug report to https://jira.mariadb.org/
      InnoDB: If you get repeated assertion failures or crashes, even
      InnoDB: immediately after the mysqld startup, there may be
      InnoDB: corruption in the InnoDB tablespace. Please refer to
      InnoDB: https://mariadb.com/kb/en/library/innodb-recovery-modes/
      InnoDB: about forcing recovery.
      210909 12:22:54 [ERROR] mysqld got signal 6 ;
      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: 10.4.20-MariaDB-1:10.4.20+maria~focal
      key_buffer_size=16777216
      read_buffer_size=131072
      max_used_connections=13
      max_threads=153
      thread_count=10
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 353082 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...
