Hi all,

The following script crashs the server (built with last bb-10.2-ext sources).

use test;
CREATE or replace TABLE `gtfmt` (
  `numgtfmt` char(10) COLLATE utf8_bin NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin;

create or replace view gtfmtl(numgtfmt)
as
select 'x' from gtfmt
union
select 'x' from gtfmt ;

SELECT * FROM gtfmtl WHERE numgtfmt =  NAME_CONST('wnumgtfmt',_utf8'QEDITIONS' COLLATE 'utf8_bin');
