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: 10.5.4-MariaDB-debug-log
 
key_buffer_size=1048576
 
read_buffer_size=131072
 
max_used_connections=1
 
max_threads=153
 
thread_count=2
 
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 63704 K  bytes of memory
 
Hope that's ok; if not, decrease some variables in the equation.

Not reproducible on 10.4.

Comment by Marko Mäkelä [ 2020-06-11 ]

I would not expect any InnoDB changes to be the culprit here. InnoDB is supposed to promote the NOT NULL UNIQUE column prefix f(8) to a PRIMARY KEY after the explicitly defined PRIMARY KEY is dropped.

What does SHOW CREATE TABLE say on 10.4 and 10.5?

Comment by Elena Stepanova [ 2020-06-11 ]

Right, it started happening after this revision:

What does SHOW CREATE TABLE say on 10.4 and 10.5?

SHOW CREATE TABLE on 10.5

 
Table	Create Table
 
t1	CREATE TABLE `t1` (
 
  `pk` int(11) NOT NULL,
 
  `f` geometry NOT NULL,
 
  UNIQUE KEY `f` (`f`(8))
 
) ENGINE=InnoDB DEFAULT CHARSET=latin1

Confirmed present on 10.5.5 30e7a0a866dce530d8328c6d614e48d39a264f9b, debug only.

Comment by Alice Sherepa [ 2022-07-15 ]

small variation, with UPDATE t1 SET f = null ORDER BY pk instead of select:
