MariaDB crashes with out-of-memory when query information_schema

Hi,

I use MariaDB in an embedded Linux system with read-only mounted datadir. Event-Scheduler is DISABLED, so I can start mysqld.

When I query information_schema tables that uses "Open_full_table; Scanned all databases" Extra on select, then the query hangs until an out-of-memory exception occurs. The mysqld daemon is restarted.

Query:

SELECT * FROM information_schema.tables

Exception:

[28200.389724] Out of memory: Kill process 4478 (mysqld) score 612 or sacrifice child [28200.412466] Killed process 4478 (mysqld) total-vm:912336kB, anon-rss:615564kB, file-rss:516kB
