10.5, 10.3(EOL), 10.4(EOL)
Description
Notes:
It looks like a variation of MDEV-18156, but MDEV-18156 patch is already in the trees, including 10.5, so it doesn't fix this one.
The test case is admittedly degenerate, but I suppose there can be more complicated and more realistic ones based on the same idea.
I've set 10.5 as an affected/fix version (contrary to our general approach of not mentioning development branches in affected/fix versions) to point out that 10.5 is indeed still affected, because MDEV-18156 was only fully fixed in 10.5.
10.3/10.4 in the fix version field are tentative, but the same consideration applies to this as to MDEV-18156: if the fix requires a new limitation in common functionality, it's probably better not to do it in post-GA releases.

Non-debug build doesn't crash, but the error is still there:
2019-10-07 0:39:53 9 [ERROR] InnoDB: Record in index `a` of table `test`.`t1` was not found on update: TUPLE (info_bits=0, 3 fields): {[4] (0x80000001),NULL,[6] (0x000000000200)} at: COMPACT RECORD(info_bits=0, 1 fields): {[8]infimum (0x696E66696D756D00)}
|
And with MyISAM it's again, with debug and non-debug:
mysqltest: At line 7: query 'UPDATE t1 SET a = 2' failed: 126: Index for table './test/t1.MYI' is corrupt; try to repair it
|
Reproducible on 10.3+.
The test case is not applicable to 10.2.
