Activity
It looks like we will have to revise the MDEV-14637 fix for this special case.
The assertion expression mentions SYS_FOREIGN and SYS_FOREIGN_COLS as a special case, because I thought that those are the only tables that would misuse CHAR(0). (The InnoDB internal SQL parser does not enforce the maximum lengths of columns.)
Testcase leading to slightly different stack

CREATE TABLE t (a INT,b INT,c CHAR(0),d CHAR(0),e BINARY (0),f VARCHAR(0),g BLOB,h BLOB,id INT,KEY(b),KEY(e)) ENGINE=InnoDB; |
INSERT INTO t VALUES (0,0,0,0,0,0,0,0,0); |

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.

I again saw the stack given in the last comment in 11.1 @ 3883eb63dc5e663558571c33d086c9fd3aa0cf8f, again without reduction being possible.
Both these cases were single threaded SQL trials. Either the given stack is highly sporadic or specific circumstance (timing, system load, state of InnoDB, shutdown...) are required for it to trigger.
In this case, it looks like only ~357 lines of SQL were required to trigger the bug, and the crash seems to clearly have happened on an INSERT statement using a sequence. The same is applicable for the last comment (note the query in the error log).
Note the # outcomes behind the queries.
ANALYZE TABLE t1;#NOERROR
|
INSERT t SELECT SEQ,SEQ+100000 FROM seq_1_to_100000;#ERROR: 2013 - Lost connection to server during query
|
DROP TABLE IF EXISTS d;#ERROR: 2006 - Server has gone away
|
Here is the resulting stack:

It seems to me that the SQL layer is not correctly enforcing the maximum length of the BINARY(0) data type, if it actually refers to an empty binary string. The test case in the Description should have been enough to conclude this. The test in the Description did not fail for me in the branch that I tried.
Warnings:
|
Warning 1265 Data truncated for column 'f' at row 1
|
If I omit the IGNORE from the INSERT statement, the warning will be promoted into an error. Deep inside InnoDB, I am seeing a zero-length key being inserted into the secondary index:

Note the two len=0 for the first field and two len=6 for the second one (the 48-bit DB_ROW_ID because no PRIMARY KEY had been defined).
Roel, can you provide access to a core dump so that I can check the data and the metadata.
This should be an SQL layer bug, because InnoDB always assumed that the SQL layer is enforcing the maximum lengths of columns.
Here is a slightly simpler test that reproduces the failure on 10.4 and 10.5:
--source include/have_innodb.inc
|
CREATE TABLE t1 (f BINARY(0), KEY (f)) ENGINE=InnoDB; |
INSERT INTO t1 SET f=''; |
DROP TABLE t1; |
On 10.6 and later, I suspect that the refactoring in MDEV-30400 removed the call to this function except when a page split or merge is necessary. So, in 10.6 and later, the table would have to be larger so that the assertion failure could be triggered.
The problem is in the logic that tries to work around the bad system table definitions of SYS_FOREIGN and SYS_FOREIGN_COLS:

The assertion would fail also due to an indexed VARBINARY(0) column.
