How to repeat:
drop table if exists `t1`;
create table `t1`(`c0` bigint,`c3` multipolygon);
insert into `t1` values 
(0,geomfromtext('multipolygon(((1 2,3 4,5 6,7 8,9 8),(7 6,5 4,3 2,1 2,3 4)))'));
select 1 from `t1` where 
`c0` <>  (select geometrycollectionfromwkb(`c3`) from `t1`);

Thank you for the report.

Verified as described.

Not repeatable with version 5.1.33.

      Bug #47780: crash when comparing GIS items from subquery
      
      If the first argument to GeomFromWKB function is a geometry
      field then the function just returns its value.
      However in doing so it's not preserving first argument's 
      null_value flag and this causes unexpected null value to
      be returned to the calling function.
      
      Fixed by updating the null_value of the GeomFromWKB function
      in such cases.

Noted in 5.0.88, 5.1.41, 5.5.0, 6.0.14 changelogs.

If the first argument to GeomFromWKB() function was a geometry value,
the function just returned its value. However, it failed to preserve
the argument's null_value flag, which caused an unexpected NULL value
to be returned to the caller, resulting in a server crash.
